Reduce TLS memory requirements for KOReader sync

Split heap gate into separate free-memory (50KB) and largest-block (20KB) thresholds based on field measurements. Enable wolfSSL single-precision ECC to use fixed 256-bit arrays instead of heap-allocated fast-math bignums, reducing TLS handshake memory footprint. Reclaim ~7KB by right-sizing ESP timer task stacks and move WiFi code out of IRAM to free ~25-30KB for heap. Add memory audit landmarks for font and EPUB allocations.
Add memory profiling for EPUB and heap diagnostics

-# CrossPoint Reader Roadmap
-
-This roadmap describes how CrossPoint is moving through the tighter scope defined in [SCOPE.md](SCOPE.md). It is
-intentionally phased: Phase 0 closed out the commitments already in flight before locking down to the stricter
-"fill gaps the stock firmware leaves" delineator.
-
-Phases are sequential. We do not start the next phase until the prior one is wrapped or explicitly carried over.
-
---
-
-## Phase 0 - Close Out Legacy Scope Items — **COMPLETE**
-
-**Goal:** Land the work that was already in motion under the prior, broader scope so contributors are not left
-hanging, and so we enter the stricter phases with a clean slate.
-
-**Landed in Phase 0:**
-
-* **RTL support PRs.** The in-flight right-to-left work was reviewed, iterated, and merged.
-* **Dictionary PR.** The offline dictionary lookup work was reviewed and merged.
-* **Bookmarks** feature. First-class navigation markers in EPUBs.
-* ~~**Transparent sleep screens.**~~ Shelved; not picked back up under the stricter phases.
-
-Phase 0 is closed. The tighter scope in [SCOPE.md](SCOPE.md) is now fully enforced. "But it was on the old roadmap"
-is not a valid argument for accepting a PR.
-
---
-
-## Phase 1 - Consolidation, Footprint, and Multi-Device Support — **IN PROGRESS**
-
-**Goal:** Reduce memory and flash usage, clean up the codebase, and land the SDK / HAL generalization work so
-CrossPoint runs cleanly on ESP32-based e-reader hardware beyond Xteink (X3 / X4), including ESP32-S3 class devices.
-
-**Focus areas:**
-
-* DRAM and heap fragmentation reduction across the reader core.
-* Flash footprint reduction (dead code, redundant strings, oversized tables).
-* Refactors that tighten the HAL / SDK boundary.
-* Pluggable per-device SDK layers (display, input, storage, battery) and per-device build configuration without
-  forking the reader core.
-* Documentation for adding a new ESP32 e-reader target.
-* E-ink driver refinement (ghosting, partial update behavior).
-
-**Closed during this phase:** new themes built into firmware, new external network connectors (sync engines, cloud
-storage, remote file access).
-
---
-
-## Phase 2 - Languages, Fonts, and Themes
-
-**Goal:** With the codebase smaller and portable, make reading great in every language: multi-language support,
-better font support with custom fonts, UI translations, and themes loaded from the SD card instead of consuming
-flash.
-
-**Focus areas:**
-
-* Multi-language reading support (underserved languages, complex script support where realistic on ESP32 hardware).
-* Better font support and custom fonts.
-* UI languages and localization.
-* Moving themes off-firmware to SD-loaded assets (see SCOPE.md Section 6).
-* **Moving hyphenation files off-firmware.** Hyphenation rules vary per language and the files are large (German
-  alone is ~200KB). Today these eat flash budget that should be available for the reader core. The plan is to build
-  a downloader analogous to the existing font downloader and store the dictionaries on SD / SPIFFS, loading on
-  demand. This unlocks better hyphenation for long-word languages (German, Finnish, Norwegian, etc.) without paying
-  the flash cost up front.
-
-This phase depends on Phase 1 cleanup landing first; otherwise we generalize a moving target.
-
---
-
-## Out of Roadmap
-
-The following are explicitly *not* on the roadmap. They may live in other CrossPoint forks; they will not be picked
-up here:
-
-* Interactive apps (games, calculators, notepads).
-* Writing / authoring tools.
-* Active connectivity features (RSS, news, browsers).
-* PDF rendering as a first-class format.
-
-See [SCOPE.md](SCOPE.md) for the full rationale.

---
-
-## How This Roadmap Changes
-
-* Phase boundaries are decided by maintainers, not by individual PRs.
-* If a phase needs to be extended or an item carried over, that is documented here with a short note.
-* Proposals for new phases or reordering should go through a Discussion first.

 # Project Vision & Scope: CrossPoint Reader

-The goal of CrossPoint Reader is to create an efficient, open-source reading experience for ESP32-based e-reader devices. Xteink hardware (X3, X4) is where the project started and remains a primary target, but CrossPoint is explicitly broadening to support the wider ecosystem of small ESP32 e-ink readers. We believe a dedicated e-reader should do one thing exceptionally well: **facilitate focused reading.**
+The goal of CrossPoint Reader is to create an efficient, open-source reading experience for the Xteink X4. We believe a
+dedicated e-reader should do one thing exceptionally well: **facilitate focused reading.**

 ## 1. Core Mission

-To provide a lightweight, high-performance firmware that maximizes the potential of ESP32-based e-reader hardware, prioritizing legibility, performance, and usability over "swiss-army-knife" functionality.
+To provide a lightweight, high-performance firmware that maximizes the potential of the X4, prioritizing legibility and
+usability over "swiss-army-knife" functionality.

-CrossPoint is **not** a kitchen-sink firmware, and it is **not** Xteink-only. We want clean, maintainable code that the community can build on, and that runs across the range of ESP32 e-reader devices (ESP32-C3, ESP32-S3, and adjacent variants). Every accepted change should make that goal easier, not harder. Device-specific code should live behind the HAL / SDK boundary so the reader core stays portable.
-
-## 2. Guiding Principle: Fill Gaps the Stock Firmware Leaves
-
-CrossPoint exists to do the things the stock firmware does poorly or not at all. New work is evaluated against that delineator:
-
-* **Does the stock firmware already do this well?** We should hit that bar or surpass it 
-* **Is another popular CrossPoint fork already solving this well?** If yes, we generally defer to that fork if it's not part of the core reading experience. e.g. stats
-* **Does this directly improve the reading experience or the firmware's long-term maintainability?** If no, it is out of scope.
-
-## 3. Current Focus
-
-We are intentionally narrowing scope to consolidate the codebase as we open it up to more ESP32 e-reader devices.
-
-During this period, the priorities are:
-
-* **Memory footprint:** Reducing DRAM usage and heap fragmentation. The ESP32-C3 is the tightest target and sets the ceiling, but the gains benefit every ESP32 variant we run on. 
-* **Flash footprint:** Trimming binary size to leave room for additional device targets and features. 
-* **Code cleanup:** Refactoring, removing dead code, tightening abstractions, and improving readability. 
-* **Reading experience:** EPUB parsing and rendering, typography, hyphenation, line spacing, font handling, and legibility improvements.
-
-### Temporarily Closed Areas
-
-PRs in the following areas will be closed until this notice is lifted. Adding these now makes the cleanup and multi-device work materially harder:
-
-* **New themes.** The existing theming surface is frozen. 
-* **New external network connectors.** This includes sync engines, cloud storage clients, OPDS extensions beyond what exists, remote file access, and any new "talk to a server" feature. We now have our own CrossPoint KOSync server which gives us a way to sync to 3rd party systems like Hardcover at an API level instead of bloating the firmware. If you're interested in helping here, the sync server is also open source.
-
-If you are unsure whether your idea falls into one of these categories, open a Discussion first.
-
-## 4. Scope
+## 2. Scope

 ### In-Scope

-*Features that directly improve the core reading experience or the firmware's maintainability.*
+*These are features that directly improve the primary purpose of the device.*

-* **EPUB Rendering & Optimization:** Improvements to the rendering engine, CSS/image handling, and parsing performance. 
-* **Typography & Legibility:** Custom font support, hyphenation, line and paragraph spacing, margins. 
-* **E-Ink Driver Refinement:** Reducing full-screen flashes (ghosting management) and improving general rendering. 
-* **Reading UX:** Bookmarks, progress tracking, button mapping, page navigation, and other in-reader interactions. 
-* **Library Management:** Simple, intuitive ways to organize and navigate a local book collection. 
-* **Memory, Flash, and Code Quality:** Refactors and cleanups that reduce resource use or improve maintainability, even without a user-visible feature.
+* **User Experience:** E.g. User-friendly interfaces, and interactions, both inside the reader and navigating the
+  firmware. This includes things like button mapping, book loading, and book navigation like bookmarks.
+* **Document Rendering:** E.g. Support for rendering documents (primarily EPUB) and improvements to the rendering
+  engine.
+* **Format Optimization:** E.g. Efficiently parsing EPUB (CSS/Images) and other documents within the device's
+  capabilities.
+* **Typography & Legibility:** E.g. Custom font support, hyphenation engines, and adjustable line spacing.
+* **E-Ink Driver Refinement:** E.g. Reducing full-screen flashes (ghosting management) and improving general rendering.
+* **Library Management:** E.g. Simple, intuitive ways to organize and navigate a collection of books.
+* **Local Transfer:** E.g. Simple, "pull" based book loading via a basic web-server or public and widely-used standards.
+* **Language Support:** E.g. Support for multiple languages both in the reader and in the interfaces.
+* **Reference Tools:** E.g. Local dictionary lookup. Providing quick, offline definitions to enhance comprehension 
+  without breaking focus.
+* **Clock Display (device dependent):** 
+
+| Device | Scope |
+| -- | -- |
+| X3 | The X3 uses a dedicated DS3231 RTC, which maintains accurate time across sleep cycles and can be treated as a reliable wall clock. |
+| X4 | The X4 relies on the ESP32-C3's internal RTC, which drifts significantly during deep sleep. NTP sync could correct this, with an appropriate user experience around connecting to the internet on wake or on demand. This causes some tension with the **Active Connectivity** section below, so please open a discussion about this UX if it's a feature you would find useful. |

 ### Out-of-Scope

-*Rejected because they compromise the device's stability, maintainability, or core mission.*
+*These items are rejected because they compromise the device's stability or mission.*

-* **Interactive Apps:** No notepads, calculators, or games. These belong in other forks and are not part of CrossPoint's focus. 
-* **Writing / Authoring Tools:** No typed notes, journals, or editors. Input hardware and RAM are wrong for this, and other forks already explore this space. 
-* **Active Connectivity:** No RSS readers, news aggregators, or web browsers. Background Wi-Fi drains the battery and complicates the single-core CPU. 
-* **PDF Rendering:** PDFs are fixed-layout documents, so rendering them requires displaying pages as images rather than reflowable text, resulting in constant panning and zooming that makes for a poor reading experience on e-ink. Out of scope on the current hardware class.
+* **Interactive Apps:** No Notepads, Calculators, or Games. This is a reader, not a PDA.
+* **Active Connectivity:** No RSS readers, News aggregators, or Web browsers. Background Wi-Fi tasks drain the battery
+  and complicate the single-core CPU's execution.
+* **Media Playback:** No Audio players or Audio-books.
+* **Complex Annotation:** No typed out notes. These features are better suited for devices with better input
+  capabilities and more powerful chips.

-## 5. Calls to Action
+### In-scope — Technically Unsupported

-These are the areas where contributor help is most valuable right now. If you want to take one of these on, open a Discussion or issue first so we can coordinate.
+*These features align with CrossPoint's goals but are impractical on the current hardware or produce poor UX.*

-### Theme System: Move Themes Off-Firmware
+* **PDF Rendering:** PDFs are fixed-layout documents, so rendering them requires displaying pages as images rather than reflowable text — resulting in constant panning and zooming that makes for a poor reading experience on e-ink.

-We want to abstract themes out of the firmware entirely so they no longer consume flash, and instead load from the SD card. This directly supports the current focus on flash footprint and code cleanup.
+## 3. Idea Evaluation

-* **Status:** [@itsthisjustin](https://github.com/itsthisjustin) plans to take this on eventually but is very open to someone else claiming it sooner. 
-* **Why it matters:** Every built-in theme costs flash that we would rather spend on rendering, fonts, or future device support. SD-loaded themes also let users customize without rebuilding firmware. It also leads to SD font loading for better language support in the UI. 
-* **How to claim:** Comment on the relevant Discussion (or open one) before starting.
+While I appreciate the desire to add new and exciting features to CrossPoint Reader, CrossPoint Reader is designed to be
+a lightweight, reliable, and performant e-reader. Things which distract or compromise the device's core mission will not
+be accepted. As a guiding question, consider if your idea improve the "core reading experience" for the average user,
+and, critically, not distract from that reading experience.

-### Identifying Other Stock-Firmware Gaps
-
-We want help cataloguing things the stock firmware (and other popular CrossPoint forks) handle poorly or not at all, so future work has a clear target list. Particularly interested in:
-
-* **RTL (right-to-left) text support:** Arabic, Hebrew, Persian, and similar scripts. 
-* **Languages with poor stock and fork coverage:** Especially those that need shaping, complex layout, or non-Latin font work that nobody is handling well today. 
-* **Other gaps:** Rendering edge cases, accessibility issues, input quirks, anything stock does badly and existing forks have not fixed.
-
-If you can read or use the device in one of these languages, your feedback (even without code) is genuinely useful. Open a Discussion with concrete examples (screenshots, sample EPUBs, expected vs actual behavior) and we will prioritize from there.
-
-## 6. Funding and Contributor Sustainability
-
-CrossPoint uses [Royalty.dev](https://royalty.dev) (yes, a product built by [@itsthisjustin](https://github.com/itsthisjustin)) to fund contributors. There has been some tension in the community around this, so the intent is being clarified here directly.
-
-**Why we do this:**
-
-* To maintain long-term interest from contributors and maintainers, in direct response to substantial community requests for a way to give back. 
-* To motivate contributors to invest in the *core* project rather than spinning up competing forks. 
-* To help pay for new ESP32 devices so we can port CrossPoint to additional hardware. 
-* To give the project a credible long-term path to sustainability.
-
-**How it works:**
-
-* Funds are distributed automatically to contributors based on impact to the codebase and tenure on the project. 
-* Over **$600** was raised in the first few hours after opening up funding, which is a signal the demand is real. 
-* The exact scoring methodology is published at <https://app.royalty.dev/transparency>.
-
-**This is not fixed in stone.** The weighting, eligibility, and distribution rules can be tweaked as we learn what works for this project. If you have concerns or suggestions about how funds are allocated, open a Discussion. The goal is a system that fairly recognizes the people doing the work, not a perfect one on day one.
+> **Note to Contributors:** If you are unsure if your idea fits the scope, please open a **Discussion** before you start

-# Touch and UI Development
-
-CrossPoint now runs on touch devices (Seeed Sticky, M5Paper, LilyGo T5) alongside the button-only Xteink X3/X4. Every screen must work with both input styles. There are two supported ways to get there:
-
-1. **New screens: build them with FreeInkUI components.** Touch hit-testing, tap highlighting, long-press, and button focus navigation come with the component; you never hand-roll coordinate math.
-2. **Existing screens and in-flight features: use the MappedInputManager touch bridge.** A small set of helpers adds tap/hold/swipe support to hand-rolled rendering without restructuring the activity.
-
-If you are starting a new activity, use FreeInkUI. If you have a feature branch with a hand-rolled screen already working on buttons, use the bridge; do not rewrite mid-flight.
-
---
-
-## Path 1: New screens with FreeInkUI
-
-FreeInkUI (`freeink-sdk/libs/ui/FreeInkUI`, namespace `freeink::ui`) is an immediate-mode component library. The core idea:
-
- While a component renders, it registers its tappable areas ("hit rects") into the frame's interaction buffer via `Frame::hit(rect, action, value, inputMask, state)`.
- Each loop you build an `InputSnapshot` from the input manager and route it against that buffer. If a tap (or mapped button press) lands in a registered rect, the routed `ActionEvent` tells you which action fired and with what value.
- Components query `frame.stateFor(action, value)` while painting, so touch-down highlight and focus states render correctly without any per-activity code.
-
-You get touch, hold highlighting, long-press, minimum touch-target sizing, and orientation-aware coordinates for free. The same action IDs fire from physical buttons, so one code path serves both input styles.
-
-### Component inventory
-
-All under `freeink-sdk/libs/ui/FreeInkUI/include/components/`:
-
-| Category | Components |
-|---|---|
-| Controls | `button`, `checkbox`, `slider`, `progress-bar`, `header` |
-| Lists | `list` (virtualized), `table`, `dropdown`, `radio-group`, `setting-row`, `toggle-row`, `stepper-row` |
-| Keyboard | `keyboard` (QWERTY/AZERTY/QWERTZ/ES layouts), `key-grid` |
-| Overlays | `popup`, `option-dialog`, `context-menu`, `message-panel`, `toast` |

-| Media | `book-card`, `cover-grid`, `cover-carousel`, `metric-card` |
-| Text | `text-field`, `text-area` |
-
-### Integration skeleton
-
-The in-tree reference is [`src/activities/util/KeyboardEntryActivity.cpp`](../../src/activities/util/KeyboardEntryActivity.cpp); it drives the FreeInkUI keyboard component inside a normal Activity. The shape:
-
-```cpp
-#include <FreeInkUIGfxRenderer.h>
-namespace fui = freeink::ui;
-
-// Render step: draw the component and (re)register its hit rects.
-fui::GfxRendererTarget target(renderer);           // adapts GfxRenderer to FreeInkUI's DrawTarget
-target.setFont(fui::GfxRendererTarget::FONT_BODY, UI_12_FONT_ID);
-const fui::DeviceContext device = target.deviceContext();  // orientation, safe area, touch sizing
-
-fui::Frame<48> frame(target, device, fui::InputSnapshot{}, interactions);  // 48 = max hit rects
-fui::KeyboardProps props;
-props.layout = &currentLayout();
-props.keyAction = ACTION_KEY;                      // one action id; the key is the event value
-props.inputMask = fui::InputTouch | fui::InputLongPress;
-fui::keyboard(frame, kbRect, props);               // draws AND registers hit rects
-```
-
-```cpp
-// Input step (each loop): feed touch state, act on routed events.
-int tx, ty, tapX, tapY, hx, hy;
-const bool pressedDown = mappedInput.wasScreenTouchDown(tx, ty);
-const bool tapped      = mappedInput.wasScreenTapped(tapX, tapY);
-const bool inContact   = mappedInput.isScreenTouchHeld(hx, hy);
-
-const auto result = touchRouter.update(interactions, pressedDown, tx, ty,
-                                       tapped, tapX, tapY, inContact, millis());
-if (result.event) {
-  activateValue(result.event.value, result.event.longPress);
-  requestUpdate();
-} else if (result.activeChanged) {
-  requestUpdate();  // repaint touch-down highlight
-}
-```
-
-Notes:
-
- `Frame<N>` is templated on the max number of hit rects; the buffer is stack/static, no heap.
- `fui::TouchHoldRouter` (see `components/keyboard/keyboard.h`) synthesizes long-press while the finger is still down and swallows the eventual release. Use it whenever a component distinguishes tap from long-press.
- For simpler screens without long-press, `FreeInkApp` / `Screen<N>` (`FreeInkApp.h`) is the ergonomic layer: it owns the interaction buffer, offers a top-to-bottom builder (`takeTop`, footer helpers, etc.), and its `render(input)` call routes the snapshot and dispatches registered action callbacks in one step. `snapshotFrom(input, device)` in `FreeInkUIInputManager.h` builds the `InputSnapshot` with orientation-aware touch mapping.
- Everything stays allocation-free and works on the button-only devices unchanged: physical buttons route through the same interaction table via each hit rect's `inputMask`.
-
---
-
-## Path 2: Adding touch to existing hand-rolled screens
-
-For activities that draw their own rows, menus, and buttons, `MappedInputManager` ([src/MappedInputManager.h](../../src/MappedInputManager.h)) exposes bridge helpers. They all return **logical screen coordinates** (orientation already applied via `GfxRenderer::tapToLogical`); never touch raw normalized panel coordinates or the SDK `InputManager` directly.
-
-| Helper | Use for |
-|---|---|
-| `wasScreenTapped(x, y)` | A completed tap (press + release), with logical coords |
-| `wasScreenTouchDown(x, y)` | Touch-down (held > 90 ms, not yet released): draw selection highlight |
-| `isScreenTouchHeld(x, y)` | Live contact position while the finger is down (drag tracking) |
-| `wasTapInRect(x, y, w, h)` | One-off hit test on a rectangle (a single button, a banner) |
-| `wasListItemTapped(index, count, selected, listTop, listHeight, hasSubtitle)` | Taps on a standard UITheme list; does the row/paging math for you |
-| `wasListItemTouchedDown(...)` | Same geometry, touch-down phase (highlight before activate) |
-| `rowTouch(row, top, rowStep, rowCount, xStart, xEnd, rowHeight)` | Any custom band of equal-height rows; returns `RowTouch::None/Down/Tap` |
-| `colTouch(col, left, colStep, colCount, yStart, yEnd, colWidth)` | Horizontal button bands (dialogs, prompts) |
-| `wasSwipe()` | Raw swipe direction if you need one beyond the global gestures |
-| `hasTouch()` | True when the device has a touch panel (rarely needed; helpers simply never fire without one) |
-
-### Pattern A: standard themed list
-
-One call per loop; UITheme owns the row geometry ([EpubReaderBookmarksActivity.cpp:123](../../src/activities/reader/EpubReaderBookmarksActivity.cpp)):
-
-```cpp
-int tapped = -1;
-if (mappedInput.wasListItemTapped(tapped, bookmarks.size(), selectorIndex, listY, listHeight, true)) {
-  selectorIndex = tapped;
-  openBookmark();
-  return;
-}
-```
-
-### Pattern B: custom rows with hold highlight
-
-For non-theme row layouts, use `rowTouch` and distinguish `Down` (highlight) from `Tap` (activate), as in [EpubReaderFootnotesActivity.cpp](../../src/activities/reader/EpubReaderFootnotesActivity.cpp):
-
-```cpp
-int row = -1;
-const auto touch = mappedInput.rowTouch(row, listTop, lineHeight, visibleCount,
-                                        contentX, contentX + contentWidth);
-if (touch != MappedInputManager::RowTouch::None) {
-  const int touched = scrollOffset + row;
-  if (touch == MappedInputManager::RowTouch::Down) {
-    if (selectedIndex != touched) { selectedIndex = touched; requestUpdate(); }
-  } else {  // RowTouch::Tap
-    selectedIndex = touched;
-    activateSelection();
-  }
-  return;
-}
-```
-
-The `Down` state exists because e-ink repaints are slow: highlight on touch-down gives immediate feedback, activation happens on release.
-
-### Global gestures: do not reimplement these
-
-Three gestures are handled once, for every screen. Activities must not add their own edge-swipe handling:
-
-| Gesture | Trigger | Where it is handled |
-|---|---|---|
-| Back | Right-swipe starting in the left 25% of the screen | Folded into `Button::Back`, so the existing `wasPressed(Button::Back)` in your activity already fires |
-| Home | Up-swipe starting in the bottom 14% | `ActivityManager::loop()`; pops to Home (activities can override via `handleHomeGesture()`) |
-| Menu | Down-swipe starting in the top 14% | Activities that have a menu check `wasMenuGesture()` themselves (the reader does this) |
-
-Because the back gesture arrives as `Button::Back`, most button-era activities gain back-swipe support with zero changes. That is the bar to aim for: bridge helpers should make touch an additive layer over the button flow, not a second input state machine.
-
-### Bridge rules
-
- Handle touch in `loop()` next to the existing button handling, one helper call per interaction zone, and `return` after consuming an event (mirrors the button pattern).
- Never call the SDK `InputManager` or read GPIO directly; the HAL rule from the main guide applies to touch too.
- Coordinates from the helpers are logical and orientation-correct on all four rotations; test at least Portrait and one Landscape mode before PR.
- Nothing to clean up in `onExit()`; the helpers are stateless from the activity's point of view.

-## Building and testing on non-Xteink devices
-
-Each MCU family is its own binary: X3/X4 are ESP32-C3, Sticky and LilyGo T5 are ESP32-S3, M5Paper v1.1 is a classic ESP32. The Sticky env ships in `platformio.ini` (`pio run -e sticky`). Envs for other devices go in **`platformio.local.ini`**, a gitignored file that PlatformIO merges over `platformio.ini` (see `extra_configs`). Create it next to `platformio.ini`; personal envs, ports, and debug flags live there and never get committed.
-
-Both envs below extend the repo's `[base]`, so they build against the `freeink-sdk` submodule with all the normal deps and scripts.

-  m5stack/M5GFX @ 0.2.20
-```
-
-Then `pio run -e m5paper_v11 -t upload` (or `-e lilygo_t5s3`). Gotchas worth knowing:
-
- **Flash mode matters.** The M5Paper is `qio`; the X4-family standalone envs need `dio`. A wrong flash-mode header boots into a `partition 0 invalid magic number 0xffff` loop even though esptool verified the write.
- **One `FREEINK_DEVICE_*` flag per env** selects the board profile (pins, panel, touch controller) from the SDK's `BoardConfig`. See `freeink-sdk/platformio.sample.ini` for reference envs of every supported device.
- **Serial logs:** `[base]` does not enable logging; without `-DENABLE_SERIAL_LOG` a non-default env prints nothing.
- No touch hardware on your desk? The X4 build still exercises the same code paths through buttons; touch-specific behavior (tap zones, gestures) needs a real device.

-# Dictionary
-
-Look up words while reading an EPUB using an offline StarDict dictionary stored on the SD card.
-
-## Supported Format
-
-The reader supports **StarDict** dictionaries. When searching for dictionaries online, look for "StarDict format" or files with `.dict`, `.idx`, and `.ifo` extensions.
-
-A dictionary folder must contain:
-
- `.idx` — word index (required, **must be uncompressed** — a `.idx.gz` will not work; decompress it on your computer with `gzip -d` first)
- `.dict` or `.dict.dz` — definition data (`.dict.dz` is supported as-is; entries are decompressed on the fly during lookup)
- `.ifo` — metadata (optional)
-
-Not supported: `.syn` synonym files (ignored), dictionaries with 64-bit index offsets (`idxoffsetbits=64` in the `.ifo` — rare, and rejected with an error), and HTML-formatted definitions render as raw markup rather than styled text.
-
-## Setting Up a Dictionary
-
-1. Copy your dictionary folder(s) to `/dictionaries/` on the SD card — one dictionary per folder, e.g. `/dictionaries/webster/webster.idx` + `webster.dict.dz`. A hidden `/.dictionaries/` folder (dot-prefixed) works the same way, for keeping it out of the file browser.
-2. Open **Settings → Reader → Dictionary** on the device.
-3. Select a dictionary from the list, or **None** to disable lookups.
-
-The Dictionary setting only appears when at least one usable dictionary folder exists. Folders containing more than one dictionary (multiple `.idx` stems) are skipped as ambiguous.
-
-## Looking Up a Word
-
-Two ways to start a lookup while reading:
-
- Open the reader menu (**Confirm**) and choose **Look Up**.
- Or set **Settings → Controls → Long-press Menu** to "Dictionary", then hold **Confirm** (~0.4s) on the reading page.
-
-One word on the page becomes highlighted:
-
-1. Use **Left/Right** to move between words in reading order, and the side **Up/Down** buttons to jump between lines.
-2. Press **Confirm** to look up the highlighted word.
-3. Press **Back** to return to the reader.
-
-On the very first lookup with a dictionary (and again if the dictionary file changes), the reader shows *"Indexing dictionary…"* while it builds a small `.qidx` sidecar file next to the `.idx`. This takes a few seconds for large dictionaries and makes all subsequent lookups fast. The sidecar can be deleted safely at any time — it will simply be rebuilt.
-
-### How Lookup Works
-
-1. **Direct match** — the word is found as-is (case-insensitive) in the dictionary index. Surrounding punctuation is ignored.
-2. **Stemming** — on a miss, common English word forms are retried automatically: possessives and plurals (`dogs` → `dog`, `stories` → `story`) and verb endings (`walked` → `walk`, `running` → `run`, `making` → `make`).
-3. **Not found** — a short popup appears and you return to word selection.
-
-## The Definition Screen
-
-When a word is found, the definition screen shows the matched headword at the top and the definition text below, with a page counter for long definitions.
-
- **Left/Right** or side **Up/Down** — previous / next page
- **Back** — return to word selection

Author	SHA1	Message	Date
Justin Mitchell	a86a644adc	Reduce TLS memory requirements for KOReader sync Split heap gate into separate free-memory (50KB) and largest-block (20KB) thresholds based on field measurements. Enable wolfSSL single-precision ECC to use fixed 256-bit arrays instead of heap-allocated fast-math bignums, reducing TLS handshake memory footprint. Reclaim ~7KB by right-sizing ESP timer task stacks and move WiFi code out of IRAM to free ~25-30KB for heap. Add memory audit landmarks for font and EPUB allocations.	2026-07-14 14:53:41 -04:00
Justin Mitchell	02398c8a96	Add memory profiling for EPUB and heap diagnostics Adds residentBytes() and cssRuleCount() methods to track EPUB memory usage including parsed CSS. Enhances memory audit logging with EPUB heap usage, max allocatable block size, and CSS rule count. Implements one-shot heap block map dump on first settled audit to identify fragmentation and long-lived allocations.	2026-07-14 13:21:15 -04:00
Justin Mitchell	ba92cb902e	Add heap memory reporting for fonts and sections Implements reportMemory() methods across SdCardFont, SdCardFontManager, and Section classes to track resident heap usage. Adds heap audit logging in EpubReaderActivity to attribute memory to fonts, framebuffer, section data, and other components for measurement-driven optimization.	2026-07-14 12:08:29 -04:00
Justin Mitchell	4d19d38152	Add idle-time glyph prewarming for next page Preload glyphs for the next page during idle time to reduce page-turn latency. After a 400ms debounce period, scan the next page in FCM scan mode (no pixels drawn) to cache missing glyphs from SD card, avoiding ~100ms of SD reads during the actual page turn. Prewarm is deferred when rendering is active, heap is low, or during rapid page-flipping.	2026-07-14 11:26:07 -04:00
Justin Mitchell	302c0771dd	Batch file list responses to reduce TCP segments Buffer JSON file list entries into ~1.4KB batches before sending to avoid one TCP segment per file. This eliminates client delayed ACK delays that were causing large directory listings to take tens of seconds. Falls back to per-entry sends if buffer allocation fails.	2026-07-14 05:15:00 -04:00
Justin Mitchell	c1a396c1ba	Stop BLE before initializing WiFi in activities Explicitly stop the BLE stack before bringing up WiFi in CrossPointWebServerActivity, FontDownloadActivity, and OtaUpdateActivity. On ESP32-C3, the shared radio and heap between BLE and WiFi stacks causes WiFi to be permanently starved if initialized while NimBLE's ~50KB is still resident, as the WiFi driver sizes its RX/TX buffer pools at init time.	2026-07-14 05:04:22 -04:00
Justin Mitchell	078d9ef535	Update status bar immediately on BLE connect/disconnect Previously the status bar showed 'BT connecting' until the next page turn. Now monitors connection state in loop() and redraws the status bar immediately when connection completes or disconnects, restoring the chapter/book title. The connecting message now takes over the entire title slot instead of prepending to it.	2026-07-14 04:47:48 -04:00
Justin Mitchell	17e4230068	Add async display refresh to overlap CPU work Introduces non-blocking display refresh methods that allow CPU work (like grayscale rendering) to overlap with the e-ink panel's refresh time. The async path starts the waveform and returns immediately, with the caller responsible for waiting via waitRefreshComplete(). Falls back to blocking refresh when fadingFix is enabled or the panel lacks deferral support.	2026-07-14 04:42:27 -04:00

Justin Mitchell	4c5fd653c0	Add Bluetooth status icon to reader status bar Display a Bluetooth icon in the status bar when BLE is connected. Also optimize memory management by lending the framebuffer instead of immediately tearing down BLE when heap is low, allowing BLE to remain active during rendering.	2026-07-09 00:13:54 -04:00
Justin Mitchell	05c1e9aa46	Add framebuffer lending for memory-intensive builds Temporarily release framebuffer memory during section pagination to reduce heap pressure. The framebuffer can be released before memory-intensive operations and restored afterward, allowing BLE stack startup threshold to be lowered from 80KB to 70KB. Implements RAII-style FrameBufferBuildLoan class to ensure proper cleanup and automatic restart on restoration failure.	2026-07-09 00:04:11 -04:00

Justin Mitchell	6f0707e83c	Suppress cppcheck warnings for CI compatibility Add missingInclude suppression to prevent false positives on fresh CI checkouts where include paths are unresolved. Add inline suppression for constVariableReference warning where cppcheck cannot detect mutations without full include path resolution.	2026-07-06 08:55:24 -04:00
Justin Mitchell	7b6df60a54	Shrink NimBLE footprint to prevent stack overflow Reduce BLE stack memory usage from ~68KB to ~52KB by disabling unused NimBLE roles (peripheral, broadcaster), limiting connections to 1, and reducing buffer counts for ACL, HCI events, and ATT entries. Remove unused cloud components (esp_insights, esp_rainmaker) that require unavailable server certificates. These changes prevent stack collision with the render shed, eliminating restart flaps on the reader device.	2026-07-06 08:48:44 -04:00
Justin Mitchell	1c13913713	Implement keep-if-fits buffer reuse to reduce heap fragmentation Replace per-page buffer free+realloc pattern with capacity tracking that only reallocates when needed size exceeds current capacity. This prevents heap fragmentation from non-coalescing holes that occurred when each page's freed block rarely fit the next page's allocation. After a few page turns, capacities converge on the book's maximum and page turns stop touching the allocator entirely.	2026-07-06 08:30:17 -04:00
Justin Mitchell	613371b716	Add heap pressure management for BLE and rendering Prevent OOM aborts by shedding BLE stack when free heap drops below 24KB before rendering. Lower BLE start threshold from 100KB to 80KB to match steady-state heap levels (~84KB). Reserve vector capacity upfront in page parsing to avoid reallocation crashes on fragmented heaps. Gate background section builds on heap availability.	2026-07-06 08:12:11 -04:00
Justin Mitchell	0d7a84e3c5	Rename variable count to scanCount for clarity Improves code readability by using a more descriptive variable name that better indicates the variable holds the device count from a BLE scan.	2026-07-06 02:23:04 -04:00

Nick	ad3138983b	fix: clear the BT-paused popup with an immediate redraw (toast semantics) The popup lingered until the next page turn. E-ink has no free timers -- clearing costs a refresh whenever it happens -- so request the redraw right away: the popup shows for the ~2 s page re-render, then clears.	2026-07-02 17:25:34 -05:00
Nick	793685e76b	feat: user path to resume BT from low-memory pause via reader menu toggle Field session: after a recovery teardown the heap settles at ~72 KB -- below the 100 KB start floor -- and never recovers on its own (the defrag silent-restart only fires when a build FAILS, and builds succeed now). BT stayed paused forever, the menu toggle claimed ON, and toggling off/on changed nothing. - Menu label tells the truth: ON / PAUSED (enabled but stack down) / OFF (new STR_STATE_PAUSED string) - Toggling BT on below the heap floor silent-restarts into the current book: the fresh boot's ~118 KB passes the gate and BT auto-starts on resume. Explicit user intent is the right trigger for the defrag. - Hoist the floor to bleinput::kStartMinFreeHeap, shared by the lifecycle gate and the toggle	2026-07-02 17:25:34 -05:00
Nick	551d29744a	fix: stop BLE lifecycle oscillation after build recovery The 70 KB restart floor was arithmetic nonsense: NimBLE takes ~57 KB, so a restart at 70 KB free left ~13 KB -- below the 40 KB build pre-flight -- so the next chapter build instantly re-entered recovery and tore BLE back down. Field symptom: endless 'BT Connecting...' popup + redraw loop. - Single conservative floor: 100 KB (57 KB stack + 40 KB build headroom) - 30 s cool-down after any recovery teardown before the lifecycle may restart BLE, so a marginal heap can never flap; the 'BT paused (low memory)' popup shows instead and reading continues without the remote	2026-07-02 17:25:10 -05:00
Nick	74a0969cc6	fix: pre-flight heap floor before section builds; no inline BLE restart Layout code (line-break DP arrays, CSS lookups, glyph buffers) allocates via std::vector/std::string and abort()s on OOM under -fno-exceptions -- it cannot fail cleanly mid-build. Field crashes (X4, BLE resident): builds entered at ~11 KB free and aborted in ParsedText:: computeLineBreaks; an inline BLE restart after recovery re-starved the render and abort()ed in FontCacheManager's scanText_.reserve at ~8 KB. - BUILD_MIN_FREE_HEAP (40 KB): pre-flight before the build; below the floor go straight to recovery instead of attempting a doomed build - Recovery no longer restarts NimBLE inline; the lifecycle stays paused until the render completes (scoped unpause guard), then the main-loop lifecycle restarts BLE behind its own heap gate	2026-07-02 17:24:29 -05:00
Nick	06aa1ac2f7	feat: silent-restart defrag on section-build double failure + BLE debug flags - EpubReaderActivity: when a section build fails even after the BLE teardown/retry, silentRestartToReader() as last-resort heap defrag, guarded by bootWasSilentRestart() to prevent reboot loops - main/SilentRestart.h: expose bootWasSilentRestart() - platformio.ini: enable FREEINK_BLE_HID_REPORT_DEBUG in env:default	2026-07-02 17:20:51 -05:00

Justin Mitchell	28d0d6f5d2	Replace range-based for loop with std::fill Use standard algorithm std::fill instead of manual loop to clear bleKeyMap array. This is more idiomatic C++ and expresses intent more clearly.	2026-06-24 17:15:44 -04:00
Justin Mitchell	568831f232	Update freeink-sdk submodule Update freeink-sdk submodule from b026965 to a913bb3.	2026-06-24 17:10:58 -04:00
Justin Mitchell	d6f5be6b7a	Add keepsBluetoothAlive hook to Activity base class Introduces a virtual method allowing activities to indicate whether they need the BLE stack to remain active. This enables selective teardown of Bluetooth to free heap memory, with the Bluetooth settings screen being able to override this for pairing and scanning functionality.	2026-06-24 17:00:52 -04:00
Justin Mitchell	d30fde2f4d	Add Bluetooth connecting popup message Add new translation string for displaying a popup message while Bluetooth connection is in progress.	2026-06-24 16:21:49 -04:00
Justin Mitchell	6305777b22	Retry EPUB section build after freeing BLE stack When building an EPUB section fails with Bluetooth enabled, temporarily stop the BLE stack to free up memory (~16KB), retry the build, then restart BLE. This works around memory fragmentation caused by the NimBLE stack that prevents allocating the large contiguous buffer needed for inflate/deflate operations. The recovery only runs once per uncached chapter since chapters are cached afterwards.	2026-06-24 16:13:43 -04:00
Justin Mitchell	9ab0b0bfb7	Add Bluetooth HID remote control support Integrate BLE keyboard host functionality for page-turner remotes. Adds device pairing, button mapping, preset configurations for Free2/Free3 remotes, and persistent storage of mappings. Migrates from open-x4-sdk to freeink-sdk submodule which includes the BleKeyboardHost library. Implements CPU frequency locking during BLE operations to prevent watchdog timeouts.	2026-06-24 15:36:29 -04:00
