## 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
Closes#930

## 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.
Sample from a Japanese text XTC

## Summary
* Add support for configuring and using multiple OPDS servers, replacing
the previous single-server limitation. Closes
https://github.com/crosspoint-reader/crosspoint-reader/issues/1178
* New OpdsServerStore singleton (modeled after WifiCredentialStore) that
persists up to 8 OPDS servers to /.crosspoint/opds.json with MAC-based
password obfuscation.
* One-time migration from legacy single-server fields in
CrossPointSettings to the new store on first boot.
* New OpdsServerListActivity for the device UI — works in two modes: a
settings list (add/edit/delete servers) and a picker (select which
server to browse). When only one server is configured, the picker is
skipped automatically.
* Renamed CalibreSettingsActivity → OpdsSettingsActivity for clarity. It
now edits individual OpdsServer entries (name, URL, username, password,
delete).
* OpdsBookBrowserActivity now receives an OpdsServer at construction and
uses its credentials for all fetches/downloads, and shows the server
name in the header.
* HttpDownloader::fetchUrl and downloadToFile accept optional per-call
username/password parameters instead of reading from global settings.
* REST API endpoints on CrossPointWebServer: GET /api/opds, POST
/api/opds, POST /api/opds/delete — passwords are never exposed over the
API (only a hasPassword flag), and omitting the password field on update
preserves the existing one.
* Web UI (SettingsPage.html) with dynamic OPDS server management cards —
add, edit, save, and delete servers from the browser.

src="https://github.com/user-attachments/assets/a8f18d84-4204-46a0-bb31-b73d24b3255f"
/>
## Additional Context
* The OpdsServerStore JSON format and obfuscation scheme are identical
to WifiCredentialStore, so the same JsonSettingsIO infrastructure
handles both.
* The web API uses POST /api/opds/delete instead of DELETE /api/opds
because the ESP32 WebServer doesn't support the DELETE method with a
request body.
* Existing single-server configurations are migrated automatically — no
user action required. After migration the legacy CrossPointSettings
fields are cleared so it only runs once.
* The HttpDownloader changes are backward-compatible: the credential
parameters default to empty strings, so existing callers are unaffected.

## Summary
Make this more transparent in Spanish:
`STR_AUTO_TURN_PAGES_PER_MIN: "Auto Turn (Pages Per Minute)"`
A weakness of the current translation is that the verb used is "to
read", but it's not clear that it is the user who will be reading a
certain amount of pages per minute. I've replaced it with the verb for
"to turn (pages)" which is the (analogous) physical action happening
regardless of who executes it, and the abbreviated adverb to clarify
that this is an automatic process. Lastly, a clarification of what the
number means in a simple proportion: "X pages in a minute". The Spanish
is very good overall, this one string is very hard to do in such a short
space. Even more so given that the number cannot be accompanied by any
units, so it must be clear from the text alone what it means.

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

## Summary
**What is the goal of this PR?**
Adds OPDS search support, allowing users to search a catalog directly
from the book browser when the server exposes an OpenSearch template.
**What changes are included?**
- `OpdsParser`: parses the OpenSearch template URL from feed-level
`<link rel="search">` elements and exposes it via `getSearchTemplate()`
- `OpdsBookBrowserActivity`: fetches and stores the search template
after each feed load; shows a Search hint on the Left button when a
template is available; launches the existing `KeyboardEntryActivity` for
query input; URL-encodes the query and fetches the result feed
- Absolute search result URLs are handled correctly in `fetchFeed`
(skips prepending the server base URL)
- A `consumeConfirm` guard prevents the Confirm release that submits the
keyboard from immediately triggering a book download on the first
browsing frame after search results load
## Additional Context
- Search is silently unavailable if the server does not advertise an
OpenSearch template — no UI change in that case
- Tested against a Calibre-Web OPDS endpoint which exposes `<link
rel="search" type="application/opensearchdescription+xml">`
- The inline URL encoder in `performSearch` was necessary as
`StringUtils` has no such utility; worth considering extracting to
`StringUtils` in a follow-up
- No new dependencies introduced

Description
This Pull Request introduces Turkish language support to CrossPoint
Reader firmware.
Key Changes:
- Translation File: Added lib/I18n/translations/turkish.yaml with 315
translated
string keys, covering all system UI elements.
- I18N Script Update: Modified scripts/gen_i18n.py to include the "TR"
abbreviation mapping for Turkish.
- System Integration: Regenerated I18N C++ files to include the new
Language::TR
enum and STRINGS_TR array.
- UI Availability: The language is now selectable in the Settings menu
and
correctly handles Turkish-specific characters (ç, ğ, ı, ö, ş, ü).
- Documentation: Updated docs/i18n.md to include Turkish in the list of
supported languages.
Testing:
- Verified the build locally with PlatformIO.
- Flashed the firmware to an Xteink X4 device and confirmed the Turkish
UI
renders correctly.
