## Summary
* **What is the goal of this PR?** (e.g., Implements the new feature for
file uploading.)
Allow users to better manage their epub library by offloading unwanted
or finished books and other files. Resolves#893
* **What changes are included?**
Added Delete Book shortcut in the fil browser. Delete function
implements the new ConfirmationActivity to show file name and solicit
user interaction before either returning to the file browser on a press
of the back button, or proceeding to delete. Delete function then
deletes the file and returns user to the file browser menu at the
current directory. Video of it working on my machine attached here:

## Additional Context
* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks,
specific areas to focus on).
Certainly potential risks associated with file deletion. Please let me
know if there are any concerns that need to be better addressed. I think
this is a very good feature to have to go along with the new screenshots
so you don't get stuck with a bunch of extra files on your device. Also
I did add this to the user guide.

## Summary
Fix https://github.com/crosspoint-reader/crosspoint-reader/issues/1137
Introducing `HalFile`, a thin wrapper around `FsFile` that uses a global
mutex to protect file operations.
To test this PR, place the code below somewhere in the code base (I
placed it in `onGoToRecentBooks`)
```cpp
static auto testTask = [](void* param) {
for (int i = 0; i < 10; i++) {
String json = Storage.readFile("/.crosspoint/settings.json");
LOG_DBG("TEST_TASK", "Read settings.json, bytes read: %u", json.length());
}
vTaskDelete(nullptr);
};
xTaskCreate(testTask, "test0", 8192, nullptr, 1, nullptr);
xTaskCreate(testTask, "test1", 8192, nullptr, 1, nullptr);
xTaskCreate(testTask, "test2", 8192, nullptr, 1, nullptr);
xTaskCreate(testTask, "test3", 8192, nullptr, 1, nullptr);
delay(1000);
```
It will reliably lead to crash on `master`, but will function correctly
with this PR.
A macro renaming trick is used to avoid changing too many downstream
code files.

## Summary
* **What is the goal of this PR?** (e.g., Implements the new feature for
file uploading.)
Fixes a clarity issue regarding the translation string `STR_SET`. The
issue lies in the fact that the english word can have different
meanings.
The only time the string is used is in the language selectio screen,
where it has the meaning of _selected_. (As in _The language has been
**set** to French_).
Another meaning can be _configured_. (As in _The KOReader username has
been __set__). This is the meaning many of the translations have taken.
The reason that the string is right above `STR_NOT_SET` (which is meant
as _not configured_).
With this PR I propose to explicitly use the term "_Selected_". There
are two good reasons for this:
+ it removes the confusion and the misleading translations
+ it is consistent with the button label `Select`, communicating the
link between the two (the row will be marked `Selected` if you press the
buttpn `Select`. Much clearer than now)
* **What changes are included?**
Removed the unused strings and added translations for the new string
`STR_SELECTED` for the languages I know.

the Issue was introduced in #1020. Previously, if a language was
selected it was marked with `[ON]` (`STR_ON_MARKER`). I considered
reverting it back to that, but the solution I described above seemed
superior.

## Summary
**What is the goal of this PR?** Implement support for footnotes in epub
files.
It is based on #553, but simplified — removed the parts which
complicated the code and burden the CPU/RAM. This version supports basic
footnotes and lets the user jump from location to location inside the
epub.
**What changes are included?**
- `FootnoteEntry` struct — A small POD struct (number[24], href[64])
shared between parser, page storage, and UI.
- Parser: `<a href>` detection (`ChapterHtmlSlimParser`) — During a
single parsing pass, internal epub links are detected and collected as
footnotes. The link text is underlined to hint navigability.
Bracket/whitespace normalization is applied to the display label (e.g.
[1] → 1).
- Footnote-to-page assignment (`ChapterHtmlSlimParser`, `Page`) —
Footnotes are attached to the exact page where their anchor word
appears, tracked via a cumulative word counter during layout, surviving
paragraph splits and the 750-word mid-paragraph safety flush.
- Page serialization (`Page`, `Section`) — Footnotes are
serialized/deserialized per page (max 16 per page). Section cache
version bumped to 14 to force a clean rebuild.
- Href → spine resolution (`Epub`) — `resolveHrefToSpineIndex()` maps an
href (e.g. `chapter2.xhtml#note1`) to its spine index by filename
matching.
- Footnotes menu + activity (`EpubReaderMenuActivity`,
`EpubReaderFootnotesActivity`) — A new "Footnotes" entry in the reader
menu lists all footnote links found on the current page. The user
scrolls and selects to navigate.
- Navigate & restore (`EpubReaderActivity`) — `navigateToHref()` saves
the current spine index and page number, then jumps to the target. The
Back button restores the saved position when the user is done reading
the footnote.
**Additional Context**
**What was removed vs #553:** virtual spine items
(`addVirtualSpineItem`, `isVirtualSpineItem`), two-pass parsing,
`<aside>` content extraction to temp HTML files, `<p class="note">`
paragraph note extraction, `replaceHtmlEntities` (master already has
`lookupHtmlEntity`), `footnotePages` / `buildFilteredChapterList`,
`noterefCallback` / `Noteref` struct, and the stack size increase from 8
KB to 24 KB (not needed without two-pass parsing and virtual file I/O on
the render task).
**Performance:** Single-pass parsing. No new heap allocations in the hot
path — footnote text is collected into fixed stack buffers (char[24],
char[64]). Active runtime memory is ~2.8 KB worst-case (one page × 16
footnotes × 88 bytes, mirrored in `currentPageFootnotes`). Flash usage
is unchanged at 97.4%; RAM stays at 31%.
**Known limitations:** When clicking a footnote, it jumps to the start
of the HTML file instead of the specific anchor. This could be
problematic for books that don't have separate files for each footnote.
(no element-id-to-page mapping yet - will be another PR soon).

## Summary
* **What is the goal of this PR?** (e.g., Implements the new feature for
file uploading.)
Currently we are displaying the languages in the order they were added
(as in the `Language` enum). However, as new languages are coming in,
this will quickly be confusing to the users.
But we can't just change the ordering of the enum if we want to respect
bakwards compatibility.
So my proposal is to add a mapping of the alphabetical order of the
languages. I've made it so that it's generated by the `gen_i18n.py`
script, which will be used when a new language is added.
* **What changes are included?**
Added the array from the python script and changed
`LanguageSelectActivity` to use the indices from there. Also commited
the generated `I18nKeys.h`
## Additional Context
* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks,
specific areas to focus on).
I was wondering if there is a better way to sort it. Currently, it's by
unicode value and Czech and Russian are last, which I don't know it it's
the most intuitive.
The current order is:
`Català, Deutsch, English, Español, Français, Português (Brasil),
Română, Svenska, Čeština, Русский`

## Summary
* **What is the goal of this PR?** KOReader sync on a German-language
book would fail with an out-of-memory error when trying to open the
destination chapter after applying remote progress. The root cause was a
chain of two independent bugs that combined to exhaust the contiguous
heap needed by the EPUB inflate pipeline.
* **What changes are included?**
## Fix 1 — Hyphenation heap defragmentation (LiangHyphenation.cpp)
### What was happening
AugmentedWord, the internal struct used during Liang pattern matching,
held three std::vector<> members (bytes, charByteOffsets,
byteToCharIndex) plus a separate scores vector — a total of 4 heap
allocations per word during page layout. For a German-language section
with hundreds of words, thousands of small malloc/free cycles fragmented
the heap. Total free memory was adequate (~108 KB) but the largest
contiguous block shrank well below the 32 KB needed for the INFLATE ring
buffer used during EPUB decompression. The failure was invisible with
hyphenation disabled, where MaxAlloc stayed at ~77 KB; enabling German
hyphenation silently destroyed the contiguity the allocator needed.
### What changed
The three std::vector<> members of AugmentedWord and the scores vector
are replaced with fixed-size C arrays on the render-task stack:
```
uint8_t bytes[160] // was std::vector<uint8_t>
size_t charByteOffsets[70] // was std::vector<size_t>
int32_t byteToCharIndex[160] // was std::vector<int32_t>
uint8_t scores[70] // was std::vector<uint8_t> (local in liangBreakIndexes)
```
Sizing is based on the longest known German word (~63 codepoints × 2
UTF-8 bytes + 2 sentinel dots = 128 bytes); MAX_WORD_BYTES=160 and
MAX_WORD_CHARS=70 give comfortable headroom. The same analysis holds for
all seven supported languages (en, fr, de, es, it, ru, uk) — every
accepted letter encodes to at most 2 UTF-8 bytes after case-folding.
Words exceeding the limits are silently skipped (no hyphenation
applied), which is correct behaviour. The struct lives on the 8 KB
render-task stack so no permanent DRAM is consumed.
Verification: after the fix, MaxAlloc reads 77,812 bytes with German
hyphenation enabled — identical to the figure previously achievable only
with hyphenation off.
## Fix 2 — WiFi lifecycle in KOReaderSyncActivity
(KOReaderSyncActivity.cpp)
### What was happening
onEnter() called WiFi.mode(WIFI_STA) unconditionally before delegating
to WifiSelectionActivity. WifiSelectionActivity manages WiFi mode
internally (it calls WiFi.mode(WIFI_STA) again at scan start and at
connection attempt). The pre-emptive call from KOReaderSyncActivity
interfered with the sub-activity's own state machine, causing
intermittent connection failures that were difficult to reproduce.
Additionally, WiFi was only shut down in onExit(). If the user chose
"Apply remote progress" the activity exited without turning WiFi off
first, leaving the radio on and its memory allocated while the EPUB was
being decompressed — unnecessarily consuming the contiguous heap
headroom that inflate needed.
### What changed
* WiFi.mode(WIFI_STA) removed from onEnter(). WifiSelectionActivity owns
WiFi mode; KOReaderSyncActivity should not touch it before the
sub-activity runs.
* A wifiOff() helper (SNTP stop + disconnect + WIFI_OFF with settling
delays) is extracted into the anonymous namespace and called at every
web-session exit point:
- "Apply remote" path in loop() — before onSyncComplete()
- performUpload() success path
- performUpload() failure path
- onExit() (safety net for all other exit paths)

## 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

/>
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.
