## Summary
* **What is the goal of this PR?**
Fix incorrect power button long-press detection during shutdown/wake
verification by introducing dedicated power button timing logic.
* **What changes are included?**
* Added getPowerButtonHeldTime() to HalGPIO as a wrapper over input
manager logic
* Replaced generic getHeldTime() usage with power-button-specific timing
in verifyPowerButtonWakeup()
* Ensures shutdown/wake decision is based only on actual power button
hold duration, not any-button timing
* Minor header update for new API exposure in HalGPIO.h
## Additional Context
This fixes a bug where holding another button while briefly pressing the
power button could incorrectly trigger shutdown behavior due to shared
timing state (getHeldTime()).
The change isolates power button timing to prevent cross-button
interference and makes shutdown logic reliable during multi-button
interactions.
No behavioral changes are expected outside of power-button handling
logic.

## Summary
* **What is the goal of this PR?**
Improve the UI based on feedback from someone on discord
> Downloading ALL fonts feature.
> 1.1 Disable sleep when downloading, in my case went directly to sleep
just right after downloading.
> 1.2 It would be great to have and overall progress indicator as we
only have the indication of each font family
> 1.3 Any cancel or pause function might come in handy in case battery
is running out and then resume or retry with pending fonts
* **What changes are included?**
- Now the UI can show overall progress across every file being
downloaded in the batch, not just progress inside the current family.
- Extended `HttpDownloader::downloadToFile()` to accept a cancel flag
and abort the download.
- Rendered a cancel button in the font download UI while a download is
in progress.
- `preventAutoSleep()` in `FontDownloadActivity.h` now returns true for
`state_ == COMPLETE` and `state_ == ERROR` in addition to
`LOADING_MANIFEST` and `DOWNLOADING`
## Additional Context
Not very satisfied with how `HttpDownloader.cpp` is right now, might try
to refactor it after v1.3.0

WiFi/LWIP/netif teardown scatters long-lived allocations across the
heap, leaving ~50KB of contiguous space unrecoverable without a reboot.
Reboot the SoC on exit from any wifi-using activity to guarantee a clean
heap. An RTC_NOINIT flag survives the reboot and tells setup() to skip
the boot splash and route the user back where they came from:
- File transfer / Calibre / OPDS / Font download -> home
- KOReader sync -> currently-open EPUB
Activities check WiFi.getMode() before rebooting, so backing out of the
network mode menu without joining doesn't trigger a cycle. KOSync also
esp_wifi_stop()s after the sync result so the radio is off while the
user reads it; full teardown happens at the reboot.
## Additional Context
The silent reboot skips the booting splash screen - it visibly looks
like a screen refresh. This does cause a disconnection/reconnection blip
for developers actively pulling logs over serial, but `pio device
monitor` and the like successfully reconnect and feed in the early boot
serial.

## Summary
SD card font fixes:
- `TxtReaderActivity` needs to call `renderer.ensureSdCardFontReady` to
build the advance lookup table to support rendering with SD card fonts.
This revealed that `TxtReaderActivity` was inconsistently performing
layout with `getTextWidth`, when the renderer actually uses
`getTextAdvanceX`, which can lead to minor inconsistencies in alignment.
- Avoid allocating one big `allText` string in
`ParsedText::layoutAndExtractLines`. Instead, pass the vector of word
strings directly to `SdCardFont::buildAdvanceTable`, where the algorithm
just needs to iterate codepoints anyway.

## Summary
First of several changes to decouple and clean up SD card fonts
integration. This change eliminates SdCardFontGlobals.h:
- Simply declare the `extern SdCardFontSystem sdFontSystem` in
SdCardFontSystem.h.
- `ActivityManager::goToReader` should not care about loading SD card
fonts. Instead do the same work in `ReaderActivity::onEnter`, after the
previous activity has exited and after ReaderActivity has validated the
file path.

## Summary
Relative includes can hide inappropriate dependency relationships. In
this case, I found that lib/KOReaderSync/KOReaderCredentialStore.cpp was
dependent on src/JsonSettingsIO.h -- a lib -> app dependency, the
opposite direction dependencies should flow in this project.
This change replaces all relative includes with root-relative includes,
and corrects the KOReaderCredentialStore dependency by moving its JSON
settings serialization local to the KOReaderSync library.

## Summary
This PR introduces **Focus Reading**, a generic implementation of
artificial fixation points (similar to Bionic Reading) designed to
improve reading speed and focus by bolding the initial characters of
words. This is achieved by dynamically bolding characters during
indexing.
<img width="500" alt="Focus Reading on X3"
src="https://github.com/user-attachments/assets/94a632a5-82da-47be-957c-538b35bf84d9"
/>
### Implementation Details
#### Core Text Engine (`ParsedText`)
- Modified `ParsedText::addWord` to implement a custom bolding
algorithm. It uses a 45% ratio for bolding, with a minimum of 1
character and a maximum of 9.
- UTF-8 Safety: Integrated `utf8NextCodepoint` to ensure character
counting and string slicing occur at safe byte boundaries, preventing
corruption of multi-byte characters (e.g., accented letters or smart
quotes).
- Intelligent Tokenization: This correctly identifies and separates
"word" characters (letters, apostrophes, hyphens) from "non-word"
characters (numbers, brackets, smart quotes).
- Formatting Preservation: The logic ensures that punctuation is not
"stolen" for the bolding count and that existing styles (like italics or
underlines) are preserved across the bold/regular split.
- Processing at indexing stage reduces CPU load at render-time and
ensures layout/fit is unaffected.
- Split details are tracked with `wordIsFocusSuffix`. After splitting
and layout, suffixes are merged back into their preceding word entries
to prevent a doubling of RAM usage.
#### Settings and UI
- Version Management: Bumped `SECTION_FILE_VERSION` to `21`
- Global Settings: Added `focusReadingEnabled` to `CrossPointSettings`.
- User Interface: Added a new toggle in the "Reader" section of the
settings menu, positioned after the "Embedded Style" option.
- Localization: Added the `STR_FOCUS_READING` string
#### Plumbing
- Plumbed the `focusReadingEnabled` boolean through
`EpubReaderActivity`, `Section`, and `ChapterHtmlSlimParser` to ensure
the user's setting reaches the `ParsedText` constructor during chapter
indexing.
## Additional Context
### Files Changed
- `lib/Epub/Epub/ParsedText.h / .cpp`: Core fixation logic and UTF-8
tokenization.
- `lib/Epub/Epub/Section.h / .cpp`: Cache header updates and

Add SdCardFontFamilyInfo::pickClosestSize(targetPtSize) and have the
manager and SdCardFontSystem drive size selection from a target point
size derived from the user's font-size enum (SMALL=12, MEDIUM=14,
LARGE=16, EXTRA_LARGE=18) rather than indexing the family's sorted size
list by enum ordinal.
The ordinal-slot approach mis-selects whenever a family doesn't ship the
canonical {12,14,16,18} set: a family with only [10,14,18] would map
SMALL/MEDIUM/LARGE/EXTRA_LARGE to 10/14/18/18 — fine for SMALL but
arbitrary for the rest. Closest-pt always picks the on-disk file nearest
to the user-intended point size, with a deterministic smaller-pt
tie-break.
No change for canonical-sized families.

## Summary
Removes duplicate "Download Fonts" menu entry and adds complete
navigation support to the font download activity.
## Problem
"Download Fonts" was appearing in **both** Reader settings and System
settings, creating a confusing duplicate menu entry.
## Changes
### 1. Remove Duplicate Menu Entry
- Removed `STR_DOWNLOAD_FONTS` from `systemSettings` in
`SettingsActivity.cpp`
- "Download Fonts" now only appears in **Reader settings**, positioned
right after the font family setting
- Rationale: Font settings logically belong together in the Reader
category
### 2. Navigation Improvements
- **Single-item navigation**: Replaced manual bounds checking with
`ButtonNavigator::nextIndex()` and `previousIndex()` methods
- Navigation now wraps from last item to first (and vice versa)
- **Page navigation**: Added continuous navigation handlers
- Long-pressing up/down buttons now navigates by page
- Uses `UITheme::getNumberOfItemsPerPage()` for consistent behavior
## Files Changed
- `src/activities/settings/SettingsActivity.cpp`: Removed duplicate
entry
- `src/activities/settings/FontDownloadActivity.cpp`: Navigation
improvements
## Testing
- Build: ✅ Compiled successfully
- Device testing: Recommended before merge
## Summary
**Goal:** Fix bidirectional KOSync position matching between CrossPoint
and KOReader so that syncing in either direction lands on the correct
page with character-level accuracy.
**Changes included:**
**Download — `toCrossPoint` (server XPath → CrossPoint page)**
- **XPath ancestry mode for structured elements**: The previous
`ParagraphStreamer` only tracked `<p>` elements. Replaced with a full
ancestor-walking mode that correctly resolves XPaths pointing into
`<li>`, `<ul>`, and other structured elements. Char offset within the
target element is bounded to the matched element's content only.
- **Slash-in-attribute-value corrupts depth tracking**:
`processByteInTag()` treated every `/` byte as a self-closing tag
marker, including `/` inside quoted attribute values (e.g.
`xmlns="http://..."`, `src="Links/image.jpg"`). This drove `htmlDepth`
to 0 prematurely, causing the ancestry search to exit far short of the
target paragraph. Fixed with `inAttrQuote` tracking.
- **Off-by-one in page formula**: `intra * totalPages` rounds up
incorrectly for last-page positions. Changed to `intra * (totalPages -
1)` to map the `[0, 1]` intra fraction correctly onto the `[0,
totalPages-1]` page range. Example: page 14 of 17 was returned as 15.
**Upload — `toKOReader` (CrossPoint page → server XPath)**
- **Off-by-one in page-to-intra formula**: Symmetric fix — `pageNumber /
totalPages` changed to `pageNumber / (totalPages - 1)`, with the guard
updated from `> 0` to `> 1` to avoid division by zero.
- **`<li>`-based XPath generation**: When the current page starts on a
list item, `findXPathForProgress` now generates `ul[N]/li[M]` XPaths
rather than falling back to the preceding `<p>`. Requires the new
`listItemIndex` field in `PageLutEntry` (section cache version bumped to
23).
- **Text-node precision with correct `text()[N].M` format**: KOReader
expects `text()[N].M` where `N` is the 1-based index of the specific
text node within the element. The previous attempt generated `text().M`
(no brackets), which caused KOReader to jump to the front of the book.
Implements a per-element text-node index stack in
`XPathProgressResolver` — parallel to the existing element path stack —
that correctly tracks text node indices relative to each element. Empty
text nodes from bare anchor elements (`<a id="anchor"/>`) are
intentionally skipped, matching KOReader's own text node counting
behavior.
**Reviewer-caught bugs**
- **Double `onCloseTag()` on malformed `</br/>`**: Both the `tagIsClose`
path and the self-closing `/` check were firing, double-decrementing
`htmlDepth`. Fixed with a `!tagIsClose` guard.
- **Dangling pointer in `LOG_DBG`**:
`std::to_string(*nextParagraphPage).c_str()` passed a pointer to a
temporary destroyed before the variadic call. Fixed with `snprintf` into
a stack `char[8]` buffer.
## Additional Context
- Section cache version bumped from 22 → 23 due to the new
`listItemIndex` field in `PageLutEntry`. Users upgrading will see a
one-time re-render of all cached sections on first load — no data loss.
- The `textNodeIndexStack` in `XPathProgressResolver` is a
`std::vector<int>` that mirrors the existing `path` and `parentStates`
stacks — same depth, same lifetime. No additional heap pressure beyond
what was already present.
- All fixes verified on device with *Gentle and Lowly* by Dane C.
Ortlund (spine 21, 17 pages). Download syncs land on the correct page;
upload syncs land at the correct paragraph with character-level offset.
## Test plan
- [ ] Download: sync from KOReader → CrossPoint lands on correct page
for `text()[N].M` XPaths
- [ ] Download: ancestry correctly resolves `<li>` positions inbound
from KOReader
- [ ] Upload: sync from CrossPoint → KOReader lands within one page for
mid-paragraph positions
- [ ] Upload: sync from CrossPoint → KOReader correctly targets `<li>`
elements when page starts on a list item
- [ ] Upload: `text()[N].M` format XPaths do not cause KOReader to jump
to front of book
- [ ] Section cache version 23: delete `.crosspoint/` and verify clean
re-parse with no crashes

## Summary
* **What is the goal of this PR?** Fix KOSync failing with "Network
error" on large/complex EPUBs, and simplify the sync navigation flow by
removing the callback/result pattern.
* **What changes are included?**
This PR combines the approaches from #1855 and #1760 into a single,
cleaner solution:
**Memory fix (from #1855):**
- `EpubReaderActivity` pre-computes the local KOReader position and
chapter name, then explicitly releases `epub` and `section` before
launching `KOReaderSyncActivity`. This frees ~65KB measured on device,
giving the TLS handshake sufficient heap. The root cause was
`MBEDTLS_ERR_X509_ALLOC_FAILED` (-0x2880) when a 3-cert chain consumed
~48KB during the handshake with only ~50KB available.
- `KOReaderSyncActivity` no longer receives a `shared_ptr<Epub>` at
construction — it lazy-loads the Epub after TLS only if remote progress
is found (`ensureEpubLoaded()`).
- Added `MIN_HEAP_FOR_TLS = 55000` guard in `KOReaderSyncClient` —
returns `LOW_MEMORY` early if aggregate free heap is too low before
attempting a TLS connection.
**Navigation simplification (from #1760):**
- Replaced `startActivityForResult` + callback with
`activityManager.replaceActivity` / `activityManager.goToReader`.
Progress is saved to `progress.bin` before the epub is released
(cancel/upload paths) and in `saveProgressAndReturn` (apply remote
path). The reader re-launches from the saved position naturally via
`goToReader`, eliminating the need to reload the epub in a callback.
- Extracted `ReaderUtils::saveProgress()` as a shared helper used by
both `EpubReaderActivity` and `KOReaderSyncActivity`.
- Added `STR_SAVE_PROGRESS_FAILED` to all 22 language files for the case
where writing the synced position to SD fails.
**Orientation fix (found during device testing):**
- `EpubReaderActivity::onExit()` resets the renderer to portrait before
destruction. With `replaceActivity` the reader is fully torn down before
KOSync starts, so KOSync was always rendering in portrait even when
reading in landscape. Fixed by calling `ReaderUtils::applyOrientation`
in `KOReaderSyncActivity::onEnter()`.
## Additional Context
Heap measurements on device (large EPUB with complex CSS):
| Metric | Before | After |
|---|---|---|
| Heap before Epub release | 88,156 bytes | — |
| Heap after Epub release | — | 153,892 bytes (+65,736) |
| Heap at TLS handshake | ~50,000 bytes (fails) | ~116,384 bytes
(passes) |
| Min-free-ever during sync session | 2,600 bytes | 33,052 bytes |
| TLS result | `MBEDTLS_ERR_X509_ALLOC_FAILED` | HTTP 200 |
Tested on device: sync from inside a large EPUB in both portrait and
landscape, cancel, apply remote progress, upload local progress.

Add a complete SD card font subsystem that enables users to install and
use custom fonts beyond the three built-in families. This combines the
back-end firmware support (#1327) with the font configuration, build
pipeline, CI distribution, and user-facing management UI (#1392).
Core font system:
- Custom .cpfont binary format (v4) with multi-style support (regular,
bold, italic, bold-italic) packed into a single file per size
- On-demand glyph loading from SD card with two-pass prewarm rendering
to bulk-read glyphs per page, achieving near-flash performance for
Latin text (~697ms vs ~681ms) and viable CJK rendering (~32% slower)
- Persistent advance cache for layout measurement without SD I/O
- Overflow ring buffer for glyph cache misses during rendering
- Memory-conscious design: only advance tables kept in RAM; glyph
bitmaps, kern tables, and ligatures loaded on demand from SD
Font management:
- On-device WiFi download from GitHub Releases with manifest-based
discovery, install/update detection, and progress UI
- Web interface font upload, listing, and deletion via /fonts page
- Manual SD card copy to /fonts/ or /.fonts/ directories
- Font selection integrated into Settings > Reader > Font Family
Build pipeline:
- Declarative YAML config (sd-fonts.yaml) as single source of truth
for the 17-family font library (serif, sans, mono, accessibility)
- Python converter (fontconvert_sdcard.py) for TTF/OTF to .cpfont with
FreeType rasterization, class-based kerning, and ligature extraction
- Parallel build orchestrator with variable font instance extraction
- CI workflow publishing versioned + stable releases to a dedicated
crosspoint-fonts repository with auto-incrementing revision tags
- Centralized version constants (cpfont_version.py) shared across
build tooling and CI, with firmware headers as manual sync points
Additional fixes:
- CJK characters no longer get hyphens inserted at line breaks
- Advance table eliminates 30+ second stalls during CJK section
indexing for paragraphs with >512 unique codepoints

## Summary
Add ability to show a status bar for 1-bit XTC files (closes#1848)
Overlays a status bar (similar style to that for epubs) over the image.
Defaults to hidden, users can set to show and either top or bottom of
the screen within "Customize Status Bar" reader settings.
I've leaned toward a simple overlay approach rather than trying anything
clever e.g. resizing the original image or allowing for shifting the
image around. I think it's more straight forward for the user to create
a buffer zone when generating the XTC files.
For 2-bit image files, it'd require more work to handle the multiple
render passes so I'm holding off on that.

Now `BaseTheme` provides non-virtual `drawBatteryLeft` and
`drawBatteryRight` methods, which use a shared static
`drawBatteryOutline` implementation, and defer to a virtual
`fillBatteryIcon` implementation. In Classic and Roundraff
`fillBatteryIcon` uses a solid fill, while Lyra and Lyra Extended use a
segmented fill.
The charging indicator inside the battery was missing for Roundraff, but
is now consistent with other themes because of the shared drawing
implementation.

## Summary
With the Roundraff theme selected and no recent books, the home screen
menu shows a "Continue Reading" option and menu handling is offset by
one ("Continue Reading" actually does "Browse Files", "File Transfer"
actually does "Settings", etc.) Simple fix here is to omit the "Continue
Reading" menu item when there are no recent books.

When Power+Down is released with a slight stagger (Down before Power),
the Power release event leaked through to the activity loop, triggering
short-press Power actions like clip selection. Add a
screenshotComboActive flag that suppresses all input processing until
Power is fully released after a screenshot combo.

## Summary
Before, any sub-activity of a reader activity needed to override
`isReaderActivity` to maintain correct bookkeeping through
`ActivityManager::isReaderActivity`. We could easily miss this in any
new sub-activities. Instead, simplify so each reader activity correctly
reports and then `ActivityManager` checks for any reader activity in its
stack.

## Summary
Simplify duplicated code in `XtcReaderActivity` to use
`ReaderUtils::detectPageTurn`. This implementation is now shared with
`EpubReaderActivity` and `TxtReaderActivity`. Also deduplicated the
chapter skip time constant.

## Summary
* **What is the goal of this PR?** Fix the vertical misalignment between
the "File Manager" title and the action buttons (Upload / New Folder /
Delete Selected).
* **What changes are included?**
- `h2`: `margin-top: 0` → `margin: 0` — removes the default browser
`margin-bottom` that was inflating the height of the header-left flex
container, pushing the calculated flex center below the visual midpoint
of the title text
- `.page-header-left`: `align-items: baseline` → `align-items: center` —
ensures the title and breadcrumbs are center-aligned with each other and
with the buttons

## Summary
* **What is the goal of this PR?**
I was seeing hangs during File Transfer. Troubleshooting via serial
showed it had to do with the SHUTTING_DOWN state. Strengthened the WiFi
State Machine a bit and added self-healing. Additionally, I found it
obnoxious to need to keep referring to serial for my wifi strength, so a
dBm meter is added opposing the SSID when on the File Transfer page.
* **What changes are included?**
The dBm meter was at risk of causing rapid screen updates (if, say, we
hovered right around a threshold), so I've implemented a basic
hysteresis around this. RISING/FALLING would be more canonical variable
names, but are reserved in the framework.
## Additional Context
My X4 has a terrible antenna, apparently, and I was running into this
failure condition pretty regularly. Wifi "bars" were chosen as a
relatively pan-cultural glyph rather than relying on localization.
Tested on hardware at -83 dBm under sustained EPUB upload (60 books, ~30
MB). Transient losses up to ~14s now ride through; pre-fix the same
losses required a power-cycle after as little as a 2s blip.

## Summary
**What is the goal of this PR?**
Restore compatibility with older XTC files that use the legacy 48-byte
header layout, so they open correctly instead of failing
header/page-table validation.
**What changes are included?**
- Updates the XTC parser to accept legacy files where pageTableOffset
starts at 0x30 instead of the newer full header size.
- Avoids treating legacy header bytes as a valid chapterOffset, so older
files are not misclassified as having chapters.
- Switches XTC file size and seek operations to 64-bit-safe wrapper
calls in HalStorage, which matches the XTC format’s 64-bit offset fields
and keeps page/chapter lookups from narrowing offsets.
- Keeps the existing bounds checks and improves related logging when XTC
page loads fail.
## Additional Context
- This is a narrow compatibility fix for XTC handling. The functional
change is in the XTC parser; the HalStorage changes are supporting
wrapper methods needed by that parser update.
- Risk should be low outside XTC reading, since the HAL changes only
expose existing underlying file APIs rather than changing storage
behavior.

## Summary
The GitHub recent release API returns lots of data, including the full
release notes. For 1.2.0, that data is 30,530 bytes. The existing
OtaUpdater HTTP handler and single-buffer JSON parsing can't reliably
handle that much data in the constrained ESP32 environment.
This change does a few things:
1. Adds a very simple lib/JsonParser/StreamingJsonParser.cpp with
SAX-style callbacks to read JSON data incrementally.
2. Adds a very simple lib/JsonParser/ReleaseJsonParser.cpp building on
StreamingJsonParser, which specifically parses the GitHub release JSON
for the release version, URL, and size.
3. Updates OtaUpdater.cpp to use an instance of ReleaseJsonParser to
incrementally parse the large response it may receive from GitHub.
Building from this commit while overriding my local version to 1.1.9, I
was able to run the OTA update process ~5 times in a row successfully.
Fixes#1561 (second part, after #1805).

## Summary
The file type was shown twice in the file browser table: as a bold badge
in the **Name** column and as plain text in the **Type** column.
**Before:** badge in Name column + redundant text in Type column
**After:** badge lives exclusively in the Type column
| | Before | After |
|---|---|---|
| Folder | Name: `📁 folder` **FOLDER** · Type: `Folder` | Name: `📁
folder` · Type: **FOLDER** |

## Summary
Another follow up to #1408. That PR revised the language.bin settings
file to version 2. After merging, it occurred to me that it would make
more sense to have the language inside the overall settings.json file,
easy for users to see and change directly.
This change adds migration from language.bin to settings.json. It only
migrates from the pre-#1408 v1 language.bin format, because v2 has only
been in for a couple of commits and I don't think we need long-term
maintenance code to handle it.
#1408 had a potential long-term maintenance issue for migration. It
assumed that the enum order of languages never changes, only grows. So,
e.g. "Portuguese (Portugal)" could never be added next to "Portuguese
(Brazil)", only appended. This change includes a hardcoded frozen
ordering of the language indices as they existed at 2f969a9, and
migrates to storing a language code string in the settings.json instead
for future reordering flexibility.
Similar to the settings.bin to settings.json migration, which renames
settings.bin to settings.bin.bak, this change renames language.bin to
language.bin.bak after adding the language setting to settings.json.

## Summary
I love the new screenshot feature but I can tell that soon I'm gonna
have a folder full of screenshots and not know what's what. It would be
great if the folder could self organize.
When a screenshot is taken while reading, the filename would now include
the book title, chapter (EPUB), page number, and progress percentage.
Example: My-Great-Book_ch3_p5_42pct_12345.bmp
* **What is the goal of this PR?** (e.g., Implements the new feature for

* **What changes are included?**
## Additional Context
* Non-reader screens keep the existing screenshot-<millis>.bmp naming.

I reviewed all the changes but I don't have any experience with this
project so this is my best guess
This allows KOSync to work for files downloaded from OPDS when set to
use filename matching
## Summary
* **What is the goal of this PR?** Brings the names of files downloaded
via OPDS into line with the KOReader OPDS plugin so the files sync when
KOSync is set to filename matching
* **What changes are included?** Change the filename generated by the
OPDS browser from "\<title\> - \<author\>" to "\<author\> - \<title\>"
so it matches KOReader.
## Additional Context
* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks,
specific areas to focus on).
Both KOReader and crosspoint sanitise the filename by removing special
characters. This step seems to already use the same rules.
