## 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`

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
Closes#930

## Summary
Deduplicated battery drawing code for Roundraff theme with other themes.
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
* This change will make better use of the space available for Title and
Subtitle in the Settings (Theme: Lyra).
Instead of having a fixed maxwidth in pixels for subtitle, it will use
the whole line and shorten the longest one if needed.
So instead of: <img width="480" height="140" alt="image"
src="https://github.com/user-attachments/assets/67e4777b-10d0-4a05-b5c7-fb775776c186"
/>
It will now show: <img width="480" height="142" alt="image"

Addresses reviewer feedback from #1644:
- **Localize keyboard hint strings** — 13 hardcoded English strings
replaced with \`tr()\` macro (\`STR_KB_HINT_*\`), making them
translatable across all 22 languages (fallback to English when not yet
translated)
- **Deduplicate \`Lyra3CoversMetrics\`** — now derives from
\`LyraMetrics\` via lambda copy, overriding only \`homeCoverTileHeight\`
and \`homeRecentBooksCount\` (eliminates ~30 duplicated metric fields)
- **Unify keyboard drawing in \`BaseTheme\`** — \`drawTextField\` and
\`drawKeyboardKey\` overrides removed from \`LyraTheme\`; variability
controlled via \`keyboardKeyCornerRadius\` metric (0=Base, 6=Lyra).
Unified text field padding to 6, adopted Lyra's secondary label draw
order (main first, then secondary)
- **Add URL-optimized keyboard layout** — \`urlLayout\` with \`:\` and
\`/\` replacing \`=\` and \`,\` for easier URL input without switching
to SYM mode

## Changes
### Layout (10-column uniform grid)
- Reduced from 13/11/10 columns per row to **10 uniform columns** across
all rows
- Keyboard now uses **90% of screen width** (was ~66%)
- Row 0: Numbers `1-9, 0` with secondary symbols (`!@#$%^&*()`)
- Rows 1-3: Standard QWERTY letters
- Bottom row: `shift` | `#@!` | `___` | `←` | `OK`
### New Symbol Mode (#@!)
- New mode toggle key `#@!` / `abc` switches between letter and symbol
layouts
- Symbol layout: 4 rows (numbers, inverted symbols, paired symbols,
loose symbols)
- Covers all 95 printable ASCII characters
- **No secondary hints, no long-press** in symbol mode (simple and
direct)
- SHIFT key remains visible but **disabled** in symbol mode
### URL Mode
- In `InputType::Url`, the Space key becomes a **URL toggle** button
- Activating URL mode replaces the 4 content rows with a **3×3 grid of
URL snippets**:
- Col 0 (protocols): `https://`, `http://`, `/opds`
- Col 1 (hosts/ports): `www.`, `192.168.`, `:8080`
- Col 2 (domains): `.com`, `.org`, `.net`
- Snippets are inserted as full strings at the cursor position
- URL mode **persists** after inserting a snippet (does not
auto-deactivate)
- Column alignment: col 0 over ABC, col 1 over URL, col 2 over Del
- Up/Down navigation maps `bottomCol - 1` / `urlCol + 1`
- SHIFT disabled in URL mode
- SpecMode (`abc`) exits URL mode back to ABC
- SpecSpace (`URL`) toggles URL mode on/off; selection always stays on
the URL button
- Button styled with `KeyboardKeyType::Mode` for consistent outline
### Cursor Mode
- **Enter**: Long-press Up (500ms) while in keyboard mode
- **Exit**: Short-press Down while in cursor mode (resets
`passwordVisible`, clears toggle position)
- **Navigate**: Left/Right move cursor position within text (one
position per press, no continuous repeat)
- **Visual**:
- Keyboard mode: underline cursor (2px line + serifs)
- Cursor mode: inverted block cursor (black fill + white character)
- Block width adapts to the actual character width under cursor (minimum
6px for narrow chars like space)
- Block position includes inter-character kerning offset for correct
alignment (calculated via string-difference: `getTextWidth(before+char)
- getTextWidth(before) - getTextWidth(char)`)
- End-of-text: thin 6px block
- Password hidden: 3-part drawing (Part 1 + block + Part 3) to prevent
block overflow onto `*` characters
- Toggle position: caret ("I") cursor at saved position, `[abc]`/`[***]`
label with inverted selection
- **Inactive key styling**:
- BaseTheme: 2px outline rectangle
- LyraTheme: gray filled rounded rectangle (`Color::LightGray`)
- **Password toggle position**: in cursor mode (Password only), Hold
Right (500ms) enters toggle — caret cursor shows saved position,
`[abc]`/`[***]` label becomes selected. Press Confirm to toggle
`passwordVisible`. Press Left to restore cursor to saved position. Right
from toggle is a no-op. Down from toggle exits to keyboard.
- `cursorPos` persists between keyboard and cursor modes
### Password Mode
- `InputType::Password` enum replaces `bool isPassword` parameter
- Text is masked with `*` except for one revealed character:
- Keyboard mode: reveals character at `cursorPos - 1`
- Cursor mode: no reveal in display text (block cursor draws actual char
directly)
- **Toggle `[abc]`/`[***]`**: accessible via cursor mode — Hold Right
(500ms) enters toggle position, Confirm toggles visibility, Left exits
back to cursor. Caret ("I") shown at saved position while in toggle.
- `passwordVisible` resets to `false` when exiting cursor mode
- **Long-press Del (1.5s)**: clears all text and resets cursor to 0
### InputType Enum
- Replaced `bool isPassword` constructor parameter with `enum class
InputType { Text, Password, Url }`
- Callers updated: `WifiSelectionActivity`, `KOReaderSettingsActivity`,
`CalibreSettingsActivity`
### Contextual Tips
- `"Tips:"` header followed by context-sensitive hints, centered between
text field underline and keyboard as a block
- ABC mode: `"Hold SELECT for UPPERCASE or secondary char"` (shift ON:
`"lowercase"` variant) + `"Hold DEL to clear all text"` (only if text
not empty)
- ABC + `InputType::Url`: same + `"Press URL for snippets"`
- Symbol mode: `"Hold DEL to clear all text"` (only if text not empty)
- URL mode: `"Press ABC to exit URL mode"` + `"Hold DEL to clear all
text"` (only if text not empty)
- Cursor mode: `"Press DOWN to return to keyboard"`
### Hint Phases (cursor mode, Password only)
- **Phase 1**: `"Hold UP to edit entry"` — shown after 2× DEL press,
auto-hides after 4s, positioned below underline
- **Phase 2**: `"Press < or > to move cursor"` + dynamic password toggle
hint — shown when entering cursor mode, positioned below underline,
visible until exit
- When `!passwordVisible`: `"Hold > then press [abc] to show password"`
- When `passwordVisible`: `"Hold > then press [***] to hide password"`
- When in toggle position: `"Press < to return to cursor position"`
### Long-Press Alternative Character
- Holding Confirm (>500ms) inserts the **alternative character** instead
of the primary
- Letters: long-press inserts opposite case (e.g., `a`→`A`, `A`→`a`)
- Numbers/symbols (row 0): long-press inserts secondary (e.g., `0`→`)`,
`)`→`0`)
- Only active in ABC mode; disabled in Symbol mode and URL mode
- **`InputType::Url`**: Hold SELECT on ABC rows 1+ (letters) returns
primary character only (same as short press). Row 0 (symbols) still
returns secondary character on Hold SELECT.
### Shift (2 sticky states)
- Reduced from 3 states (shift/SHIFT/LOCK) to **2 sticky states**
(shift/SHIFT)
- Shift stays active after typing until manually toggled off
- Label: `shift` (off) / `SHIFT` (on)
### SpecialKeyType Enum
- `enum class SpecialKeyType { Shift, Mode, Space, Del, Ok }` replaces
plain `enum` (`SpecShift`, `SpecMode`, etc.) for type safety
- All switch cases updated to `SpecialKeyType::*` with
`static_cast<int>()` for array indexing
- `onExit()` reverted to simple `Activity::onExit()` call (half-refresh
removed)
- **Bottom row column mapping**: navigating up/down between content rows
and bottom row uses `col/2` and `col*2` formulas for consistent
positioning (10 cols ↔ 5 cols)
- **URL mode column mapping**: `bottomCol - 1` / `urlCol + 1` (3 cols ↔
5 cols)
- **Wrap-around**: row 0 → up → bottom row and bottom row → down → row 0
both apply correct column mapping
### Visual Improvements (both Base and Lyra themes)
- **Space key**: underscore-style horizontal line (60% of key width, 3px
thick)
- **Delete key**: arrow `←` drawn with lines (3px thick) instead of
"DEL" text
- **Secondary label** (ABC row 0): small hint in top-right corner with
separation from primary number
- **BaseTheme**: selection uses **inverted fill** (black rect + white
text) instead of `[bracket]` markers
- **BaseTheme**: text field brackets drawn as **stretchable lines** that
adapt to multi-line input (1px normal, 3px cursor mode)
- **LyraTheme**: text field uses **fixed-width underline** (16px
margins, 8px each side) instead of stretchable line (2px normal, 3px
cursor mode)
- **Both themes**: special keys (shift, mode, space, del, OK) have
bordered/bordered-rounded rectangles
- **Font size**: keyboard uses `UI_12_FONT_ID` in both themes (was
`UI_10` in Base)
- **Key height**: 40px in all themes for better proportions
- **Layout unification**: text and password toggle are left-aligned in
all themes (`keyboardCenteredText = false` for Lyra/Lyra3Covers)
- **`primaryOffset` removed**: dead code eliminated from BaseTheme and
LyraTheme `drawKeyboardKey`
### New Theme Metrics
- `keyboardVerticalOffset`: per-theme vertical adjustment of keyboard
position
- Base: `-13`, Lyra: `-7`
- `keyboardBottomKeySpacing`: independent spacing for bottom row keys
- Base: `5`, Lyra: `5`
- Bottom-aligned keyboard in both themes for consistent vertical
positioning
- Bottom row total width calculated to match content rows width (10-col
based, consistent across modes)
- 4px extra gap between content rows and bottom row when `bkSpacing > 0`
- `keyboardCenteredText`: `false` for all themes (unified left-aligned
text)
### Defensive Improvements
- **State reset on re-entry**: `onEnter()` resets all mutable state
(`symMode`, `urlMode`, `cursorMode`, `togglePos`, `passwordVisible`,
`shiftState`, `selectedRow`, `selectedCol`, `rightHeld`,
`rightLongHandled`, `savedCursorPos`, `rightStartCursorPos`,
`delPressCount`, `hintVisible`, `hintShowTime`) — prevents stale state
when re-entering the keyboard
- **Bounds checking**: `insertChar`/`insertString` clamp `cursorPos` to
`text.length()` before inserting
- **Empty string guard**: `insertString` returns early on empty string
- **`std::string::npos`**: used instead of `SIZE_MAX` for size_t
sentinel (proper C++ idiom)
- **`<algorithm>` header**: included for `std::max`

- [x] Left at position 0 → no movement
- [x] Right at end of text → no movement in Text mode, enters toggle in
Password mode (Hold Right)
- [x] Block cursor visual: correct width for character, thin block at
end
- [x] Underline cursor visual (keyboard mode): correct position with
serifs
- [x] Inactive key styling: outline (Base) or gray fill (Lyra) on
selected key
- [x] Typing with cursor mid-text → inserts at cursor position
- [x] Deleting with cursor mid-text → deletes character before cursor
- [x] Exit cursor mode → type at cursor position (inserts mid-text, not
at end)
- [x] Exit cursor mode from toggle → cursor at saved position (not end
of text)
### Password Mode
- [x] Masked text with one revealed character at `cursorPos - 1`
- [x] Cursor mode: block shows actual character, display text all `*`

### Toggle Position
- [x] Hold Right > 500ms in cursor mode (Password) → enters toggle,
caret visible at saved position
- [x] Short-press Right in cursor mode (Password) → advances cursor 1
position, does not jump to toggle
- [x] Short-press Left in cursor mode (Password) → moves cursor left 1
position, from toggle returns to saved position
- [x] Confirm in toggle → toggles `passwordVisible`
- [x] Left from toggle → returns to saved position, caret disappears,
block cursor appears
- [x] Right from toggle → no-op
- [x] Down from toggle → exits to keyboard, cursor at saved position
- [x] Hold Right in cursor mode (InputType::Text) → no effect
- [x] Hold Right in cursor mode (InputType::Url) → no effect
- [x] Hold Right < 500ms released in cursor mode (Password) → short
press, advances cursor 1
- [x] No continuous repeat when holding Left or Right in cursor mode
### Caret Visual in Toggle
- [x] In toggle: caret "I" visible at saved cursor position
- [x] Character under cursor visible (no gap) in password not-visible
mode
- [x] Character under cursor visible in password visible mode
- [x] `[abc]`/`[***]` label with inverted selection in toggle
### Contextual Tips
- [x] `"Tips:"` header centered above contextual hints
- [x] Single tip → `"Tips:"` + one line
- [x] Multiple tips → `"Tips:"` + multiple lines, all centered as block
- [x] No tips shown when not applicable (e.g., ABC with empty text and
non-URL)
- [x] `"UPPERCASE"` shown when shift OFF

### Hint Phases
- [x] 2× DEL → Phase 1 appears ("Hold UP to edit entry")
- [x] Phase 1 auto-hides after 4s
- [x] Phase 2 appears when entering cursor mode ("Press < or > to move
cursor")
- [x] Phase 2 shows "Hold > then press [abc] to show password" when
`!passwordVisible`
- [x] Phase 2 shows "Hold > then press [***] to hide password" when
`passwordVisible`
- [x] Phase 2 shows "Press < to return to cursor position" when in
toggle
- [x] Phase 2 disappears when exiting cursor mode
### Long-Press `InputType::Url` Behavior
- [x] Hold SELECT on letter rows (rows 1+) with InputType::Url → same
character as short press
- [x] Hold SELECT on row 0 with InputType::Url → secondary character
works normally
### Number Row Reorder
- [x] Number row order: 1-9, 0 left to right
- [x] `(` and `)` are adjacent (positions 8 and 9) via secondary labels
- [x] Long-press on row 0 returns correct secondary symbols in new order
- [x] SYM row 1: `(` and `)` also adjacent (positions 8 and 9)
### Block Cursor Alignment
- [x] Block cursor correctly positioned for consecutive spaces (kerning
offset applied)
- [x] Block cursor correctly positioned for mixed characters (letters,
numbers, symbols)
- [x] Block width minimum 6px for narrow characters (space) — visible as
block, not thin line
- [x] Password hidden: 3-part drawing prevents block overflow onto `*`
characters
- [x] Password visible: block post-loop draws correctly on continuous
text (no 3-part needed)
- [x] End-of-text block: thin 6px block at correct position
### Integration
- [x] WiFi password entry (connect to network)
- [ ] KOReader username, password, and sync server URL
- [ ] Calibre OPDS URL, username, and password
- [ ] Calibre OPDS URL: empty → opens with "https://" prefilled
- [ ] Calibre OPDS URL: type "http://" or "https://" only → saved as
empty
- [ ] Calibre OPDS URL: type full URL → saved correctly
- [ ] Calibre OPDS URL: existing URL → opens with existing URL (not
"https://" prefill)
## Summary
Make popups (like "Going to sleep") respect the current screen
orientation when shown from reader activities.
**What changes are included?**
- Apply reader orientation in SleepActivity before showing popup when
`lastSleepFromReader` is true
- Make popup Y-position proportional to screen height (7.5% for
BaseTheme, 16.5% for LyraTheme) instead of hardcoded pixel values,
ensuring correct positioning in both portrait and landscape modes.
- Add `isReaderActivity()` override to all reader sub-screens (menu,
chapter selection, percent selection, footnotes, QR display, KOReader
sync), so sleep popups rotate correctly when entering sleep from any
reader context.

Following up on #1427:
- Extracted shared battery drawing logic, including lightning bolt, to
reduce duplication.
- In Lyra with segmented battery the lightning bolt was hard to see, so
when charging Lyra now uses a solid battery fill.

## Summary
**What is the goal of this PR?** (e.g., Implements the new feature for
file uploading.)
`DESTRUCTOR_CLOSES_FILE=1` is set in platformio.ini, which makes SdFat's
FsBaseFile destructor call close() automatically when a file goes out of
scope.
Three categories of file close calls remain untouched:
1. Close before Storage.remove() on the same path: ScreenshotUtil.cpp
closes the file before deleting it on write error. The remove might fail
if the file is still open.
2. Close before reopening the same variable: Epub.cpp writes a temp
NCX/nav file, closes it, then reopens it for reading. The
RecentBooksStore.cpp close before saveToFile() is the same pattern, it
rewrites the same file.
3. Close on member variables: BookMetadataCache.cpp (bookFile,
spineFile, tocFile), Section.cpp (file), XtcParser.cpp (m_file),
ZipFile.cpp (file). These persist beyond any single function scope, so
the destructor timing doesn't match the intended close point.

## Summary
Adds Xteink X3 hardware support to CrossPoint Reader. The X3 uses the
same SSD1677 e-ink controller as the X4 but with a different panel
(792x528 vs 800x480), different button layout, and an I2C fuel gauge
(BQ27220) instead of ADC-based battery reading.
All X3-specific behavior is gated by runtime device detection — X4
behavior is unchanged.
Depends on community-sdk X3 support: open-x4-epaper/community-sdk#19
(merged).
## Changes
### HAL Layer
**HalGPIO** (`lib/hal/HalGPIO.cpp/.h`)
- I2C-based device fingerprinting at boot: probes for BQ27220 fuel
gauge, DS3231 RTC, and QMI8658 IMU to distinguish X3 from X4
- Detection result cached in NVS for fast subsequent boots
- Exposes `deviceIsX3()` / `deviceIsX4()` helpers used throughout the
codebase
- X3 button mapping (7 GPIOs vs X4's layout)
- USB connection detection and wake classification for X3
**HalDisplay** (`lib/hal/HalDisplay.cpp/.h`)
- Calls `einkDisplay.setDisplayX3()` before init when X3 is detected
- Requests display resync after power button / flash wake events
- Runtime display dimension accessors (`getDisplayWidth()`,
`getDisplayHeight()`, `getBufferSize()`)
- Exposed as global `display` instance for use by image converters
**HalPowerManager** (`lib/hal/HalPowerManager.cpp/.h`)
- X3 battery reading via I2C fuel gauge (BQ27220 at 0x55, SOC register)
- X3 power button uses GPIO hold for deep sleep
### Display & Rendering
**GfxRenderer** (`lib/GfxRenderer/GfxRenderer.cpp/.h`)
- Buffer size and display dimensions are now runtime values (not
compile-time constants) to support both panel sizes
- X3 anti-aliasing tuning: only the darker grayscale level is applied to
avoid washed-out text on the X3 panel. X4 retains both levels via
`deviceIsX4()` gate
**Image Converters** (`lib/JpegToBmpConverter`, `lib/PngToBmpConverter`)
- Cover image prescale target uses runtime display dimensions from HAL
instead of hardcoded 800x480
### UI Themes
**BaseTheme / LyraTheme** (`src/components/themes/`)
- X3 button position mapping for the different physical layout
- Adjusted UI element positioning for 792x528 viewport
### Boot & Init
**main.cpp**
- X3 hardware detection logging
- Adjusted init sequence for X3 (no `HalSystem::begin()` dependency on
X3 path)
**HomeActivity**
- Uses runtime `renderer.getBufferSize()` instead of static
`GfxRenderer::getBufferSize()`
FYI I did not add support for the gyro page turner. That can be it's own
PR.
## Summary

## Summary
**What is the goal of this PR?**
This change avoids the pattern of creating a `std::string` using
`.substr` in order to compare against a file extension literal.
```c++
std::string path;
if (path.length() >= 4 && path.substr(path.length() - 4) == ".ext")
```
The `checkFileExtension` utility has moved from StringUtils to
FsHelpers, to be available to code in lib/. The signature now accepts a
`std::string_view` instead of `std::string`, which makes the single
implementation reusable for Arduino `String`.
Added utility functions for commonly repeated extensions.
These changes **save about 2 KB of flash (5,999,427 to 5,997,343)**.

## Summary
This PR aims to reduce the complexity of the status bar by splitting the
setting into 5:
- Chapter Page Count
- Book Progress %
- Progress Bar
- Chapter Title
- Battery Indicator
These are located within the new StausBarSettings activity, which also
shows a preview of the bar the user has created
<img width="513" height="806" alt="image"

/>
When updating from a previous version, the user's past settings are
honoured.
## Additional Context
The PR aims to remove any duplication of status bar code where possible,
and extracts the status bar rendering into a new component - StatusBar
It also adds a new (optional) padding option to the progress bar to
allow the status bar to be shifted upwards - this is only intended for
use in the settings.

## Summary
**What is the goal of this PR?**
Improved typesetting, including
[kerning](https://en.wikipedia.org/wiki/Kerning) and
[ligatures](https://en.wikipedia.org/wiki/Ligature_(writing)#Latin_alphabet).
**What changes are included?**
- The script to convert built-in fonts now adds kerning and ligature
information to the generated font headers.
- Epub page layout calculates proper kerning spaces and makes ligature
substitutions according to the selected font.
## Additional Context
- I am not a typography expert.
- The implementation has been reworked from the earlier version, so it
is no longer necessary to omit Open Dyslexic, and kerning data now
covers all fonts, styles, and codepoints for which we include bitmap
data.
- Claude Opus 4.6 helped with a lot of this.
- There's an included test epub document with lots of kerning and
ligature examples, shown in the photos.
**_After some time to mature, I think this change is in decent shape to
merge and get people testing._**
After opening this PR I came across #660, which overlaps in adding
ligature support.

## Summary
**What is the goal of this PR?**
Small cleanup to make getTheme and getMetrics methods on UITheme const.
They return const refs, so updated call sites to use `const auto&`.
Realistically this won't make much performance difference, but it better
conveys the nature of theme metrics being shared const state.

Implements new feature for viewing .bmp files directly from the "Browse
Files" menu.
* **What changes are included?**
You can now view .bmp files when browsing. You can click the select
button to open the file, and then click back to close it and continue
browsing in the same location. Once open a file will display on the
screen with no additional options to interact outside of exiting with
the back button.
The attached video shows this feature in action:

The changes implemented in #884 are also present here as this feature is
actually what led to me noticing this issue. I figured I would add that
PR as a separate request in case that one could be more easily merged
given this feature is significantly more complicated and will likely be
subject to more intense review.

## Summary
The introduction of `HalGPIO` moved the `BatteryMonitor battery` object
into the member function `HalGPIO::getBatteryPercentage()`.
Then, with the introduction of `HalPowerManager`, this function was
moved to `HalPowerManager::getBatteryPercentage()`.
However, the original `BatteryMonitor battery` object is still utilized
by themes for displaying the battery percentage.
This PR replaces these deprecated uses of `BatteryMonitor battery` with
the new `HalPowerManager::getBatteryPercentage()` function.
