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.
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.
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.
## Summary
This PR enhances the EPUB reader's bookmark system with two
complementary improvements: a per-page bookmark indicator icon and
toggle behavior on the existing long-press action.
---
### What Changed
**Bookmark Toggle (was: add-only)**
The long-press Confirm action now toggles bookmarks rather than always
adding. `addBookmark()` checks whether a bookmark with the same xpath
already exists in the in-memory cache:
- If found → removes it and shows "Bookmark removed."
- If not found → adds it and shows "Bookmark added."
A new `STR_BOOKMARK_REMOVED` translation string was added to support the
removal message.
**Bookmark Icon Indicator**
A `BookmarkIcon` is now drawn at the top-right corner of the page
whenever the current page has a bookmark. `updateBookmarkFlag()` is
called at render time to determine whether the current page is
bookmarked.
**In-Memory Bookmark Cache**
Bookmarks are now loaded into `cachedBookmarks` on `onEnter()` rather
than being re-read from disk on every toggle. All subsequent add/remove
operations work against this cache and flush to disk, avoiding redundant
file reads on each bookmark action.
**Faster bookmarks list**
Previously, calculating "page X/Y" for each entry required decompressing
the entire spine item. We now persist `si`/`pc`/`pp` (spine index, page
count, and page progress) in the bookmark JSON when saving, and restore
them when loading. This avoids the expensive `toCrossPoint()` loop in
`onEnter()`, significantly reducing the cost of initializing the
bookmarks list.
---
### Files Changed
- `EpubReaderActivity.cpp` — `addBookmark()` toggle logic,
`updateBookmarkFlag()` (new), icon rendering in `renderContents()`,
cache initialization in `onEnter()`
- `EpubReaderActivity.h` — new fields: `currentPageBookmarked`,
`bookmarkRemoved`, `cachedBookmarks`; new method declaration
`updateBookmarkFlag()`

## Summary
* Adds a live font preview pane to the font selection screen so users
can see how a font looks before committing to it.
* Changes
* A preview pane occupying the top 30% of the font selection screen,
rendering sample pangram text in the previewed font
* A two-step confirm flow: first press (enter button) previews the font,
second press selects it
* Back restores the original font settings, so browsing has no side
effects
* Layout dimensions cached in `onEnter()` to avoid redundant
recalculation between `loop()` and `render()`
## Additional Context
* Preview sample text is hardcoded English; didn't want to use AI for
translation as I would not be able to verify the output in most
languages...
* The preview pane reduces visible list height; this is compensated by
passing the reserved height into `getNumberOfItemsPerPage`

## Summary
- Hold the menu (Confirm) button for ≥1s while reading an EPUB to launch
the existing `KOReaderSyncActivity` directly — replaces the three-step
path (open reader menu → scroll to Sync → confirm) with a single
gesture.
- Reuses `ReaderUtils::GO_HOME_MS` (same 1s threshold used by long-press
Back) and the existing `KOREADER_STORE.hasCredentials()` guard.
- Adds a Controls picker **"Long-press Menu"** (`longPressMenuFunction`,
default **Bookmark**) that **cycles through the available functions**
bound to the long-press gesture: `KOSync → Disabled → Bookmark`. The
field name and `LONG_PRESS_MENU_FUNCTION` enum are intentionally general
so future actions (dictionary lookup, table of contents, etc.) can be
appended without another schema migration. The setting is **not** a
binary toggle.
- Existing menu Sync entry still works — both call sites share one
extracted helper (`launchKOReaderSync`); no logic duplication.
- Short-press Confirm release is gated on duration so the reader menu
does not also open after a long press that *acts*, mirroring the
existing long-press Back pattern.
- **No-credentials fall-through:** `launchKOReaderSync()` now returns
whether it acted. When the function is set to KOSync but no KOReader
credentials are stored, the long-press is a no-op that **falls through
to open the reader menu** — so the menu stays reachable instead of the
hold silently swallowing the gesture. The release is only suppressed
when sync actually launched or surfaced a save error.
## Test plan
- [x] `pio run` succeeds clean for the `default` ESP32-C3 environment.
- [x] On-device, value **KOSync**, valid KOReader credentials:
long-press Confirm ≥1s → sync screen launches; get + update progress
return HTTP 200; release does **not** also open the reader menu; returns
to the same page.
- [x] On-device, value **KOSync**, **no** credentials: long-press
Confirm falls through and **opens the reader menu** (regression fix);
short-press also opens the menu.
- [x] On-device: menu → Sync still launches the same screen (shared
helper) and syncs (200/200).
- [x] On-device, value **Bookmark**: long-press drops a bookmark and
does **not** also open the menu.
- [x] On-device, value **Disabled**: long-press Confirm opens the menu
on release; no sync, no bookmark.
- [x] On-device: long-press Back still goes to the file browser
(unchanged path).
- [x] Heap: epub is released before the TLS handshake (frees ~16 KB);
min free heap stayed ~84 KB during sync, well above the safe floor. No
panics/OOM across the session.

## Summary
**What is the goal of this PR?**
Adds a clearer Quick Resume sleep-screen flow. The previous “Page as
Sleep Screen” behavior is now exposed as a dedicated `Sleep Screen >
Quick Resume `option, with the timeout-only behavior controlled by a
renamed `Quick Resume on Timeout `setting.
**What changes are included?**
- Adds `Quick Resume` as a new `Sleep Screen` option.
- Renames the old `Page as Sleep Screen` setting to `Quick Resume on
Timeout`.
- Changes that setting’s choices from `Never / After Timeout / Always`
to `OFF / ON`.
- Makes `Quick Resume on Timeout = ON` equivalent to the old `After
Timeout` behavior.
- Makes `Sleep Screen > Quick Resume` equivalent to the old `Always`
behavior.
- Automatically forces `Quick Resume on Timeout` to `ON` when `Sleep
Screen` is set to `Quick Resume`.
- Renames internal setting references from `seamlessSleepScreen` to
`quickResumeSleepScreen`.
- Updates translations for the renamed setting label.
**Additional Context**
- This is mostly a settings/labeling restructure around existing
behavior, not a new rendering path.
- The runtime quick-resume behavior still uses the existing saved
framebuffer / last-screen sleep flow.
- Review focus areas:
- Sleep entry behavior from manual sleep vs timeout sleep.
- The automatic dependency where selecting `Sleep Screen > Quick Resume`
sets `Quick Resume on Timeout` to `ON`.

**New `Quick Resume` option for `Sleep Screen` will automatically set

improvements.

New option: `Page as Sleep Screen` - `Never (default)`, `After Timeout`,
`Always`
When enabled, it seamlessly sleeps on timeout or power off, making a
fast refresh for the moon icon. When waking up, we still show the last
page, instead of the boot screen, making it fully seamless.
I tried different icons such as "refresh arrow" and others, but they
looked not as nice as 3 simple dots.
With this mode, the device turns off 4 seconds faster. And has 6 seconds
less delay when turning back on. Much more responsive.
Previously, even a 10-minute timeout sometimes wasn't enough, and I'd
worry about seeing the book cover. It's now easier to use a shorter
sleep timeout: if I get distracted during a reading session but don't
want to stop, the new screen is much more inviting to come back to.
