Jeremy Klein adcd7961c9 feat: self-heal from transient WiFi loss, add dBm indicator during WebServerActivity (#1780)
## 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.

Dave AllieandZach Nelson e026bcb9dc fix: Track block style stack for nested styles (#1582)
## Summary

* Add new block style stack to track accumulated styles
* When dropping into nested block, apply new styles on last BlockStyle
in the stack and push to the back
  * When leaving block, pop the stack
* Fix issue where the image % width always went off screen width, use
current container width based on accumulated styles
* Bump section cache version to regenerate pages

## Additional Context

Fixes https://github.com/crosspoint-reader/crosspoint-reader/pull/1581
more correctly, and includes fix from
https://github.com/crosspoint-reader/crosspoint-reader/pull/1580

  Consider:
```html
<div class="c1">          <!-- marginLeft: 10px -->
  <div class="c2">        <!-- marginLeft: 20px -->
    <p class="c3">text</p>  <!-- marginLeft: 5px -->
  </div>
  <p class="c4">text2</p>   <!-- marginLeft: 5px -->
</div>
```

| Element | Expected | Before #1581 (leaked) | After #1581 (reset) |
This PR (style stack) |
| --- | --- | --- | --- | --- |
| `c3` | 10+20+5 = 35px | 35px | 25px | 35px |
| `c4` | 10+5 = 15px | 35px (wrong, leaked c2) | 5px (wrong, lost c1) |
15px |

This PR replaces the reset-on-close approach with a proper block style
stack. When a block element opens, its resolved style is pushed onto the
stack. When it closes, the stack pops back to the parent's style. This
correctly accumulates nested margins/padding while preventing style
leakage to siblings.

Julia b692bad10d fix: support legacy XTC file headers where pageTableOffset=48 (#1816)
## 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.

Zach Nelson aa7a31b3db fix: Read GH release JSON as stream in OTA updater (#1810)
## 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).

Zach Nelson b25389b43e refactor: Move language setting into JSON settings (#1796)
## 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.

jpirnayandZach Nelson d53c8b0e0e perf: replace i18n pointer tables with offset tables, strip unused strings (#1408)
## Summary

* **What is the goal of this PR?** Reduce the flash footprint of the
i18n string data and tooling improvements to `gen_i18n.py`.

* **What changes are included?**

### 1. `lib/I18n/I18n.cpp` — use offset-based lookup

`I18n::get()` previously dereferenced a `const char* const*` pointer
array. It now uses a two-field `LangStrings` struct (a flat char blob +
a `uint16_t` offset table) generated for each language:

```cpp
// before
const char* const* strings = getStringArray(_language);
return strings[index];

// after
const LangStrings lang = getLanguageStrings(_language);
return lang.data + lang.offsets[index];
```

Lookup cost is unchanged — still O(1), one array load and one addition.

### 2. `scripts/gen_i18n.py` — new generated layout

Each language's string data is now emitted as:

- **`STRINGS_XX_DATA[]`** — a single `const char[]` blob of all strings
concatenated with `\0` separators.
- **`OFFSETS_XX[]`** — a `uint16_t` array of one byte-offset per `StrId`
into the blob.

Previously each language had a `const char* const STRINGS_XX[]` pointer
array (4 bytes/entry on ESP32-C3).

#### Flash savings

| Table type | Size per language | 19 languages |
|---|---|---|
| `const char*` pointer array (before) | `339 × 4 = 1,356 B` | **25,764
B** |
| `uint16_t` offset table (after) | `339 × 2 = 678 B` | **12,882 B** |
| **Saved** | | **12,882 B (~12.6 KB)** |

String data size is unchanged — 133,092 B across 19 languages.

**Total: 158,856 B → 145,974 B** (pointer tables → offset tables).

### 3. Build-time stripping of unused strings

`gen_i18n.py` now scans the `src/` and `lib/` trees for `STR_*`
references and, during a PlatformIO build, automatically omits the 52
strings that are defined in YAML but never referenced in code. This
further reduces the compiled output from 339 → 287 string keys per
language.

---

## `gen_i18n.py` CLI reference

```
python gen_i18n.py [translations_dir [output_dir]] [options]
```

| Argument / Flag | Default | Description |
|---|---|---|
| `translations_dir` | `lib/I18n/translations` | Path to the
per-language YAML files |
| `output_dir` | `lib/I18n/` | Where to write the generated `.h` /
`.cpp` files |
| `--src-dirs DIR [DIR …]` | `src lib` | Directories scanned for `STR_*`
usage |
| `--strip-unused` | off | Remove unreferenced `STR_*` keys from
generated output |
| `--verbose` / `-v` | off | Print per-key INFO/WARNING messages and
`Generated:` lines |

The PlatformIO build (SCons `pre:` hook) calls `main(strip_unused=True)`
automatically, so unused strings are always stripped from firmware
builds without any manual flag.

**Default run output** (no flags) shows a per-language summary table:
```
Language            Code  Own  Fallback  Unused  Data (B)
------------------  ----  ---  --------  ------  --------
English             EN    339  0         52        5,266
Belarusian          BE    310  29        52        9,673
…

  Total: 339  |  Used in code: 287  |  Never used: 52
  Flash (now):    133,092 B strings  +  12,882 B offset tables (uint16_t)  =  145,974 B
  Flash (before): 133,092 B strings  +  25,764 B pointer tables (ptr32)    =  158,856 B
  Saved by offset tables: 12,882 B

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
file uploading.)
* **What changes are included?**

## Additional Context

* Non-reader screens keep the existing screenshot-<millis>.bmp naming.

14e1ce2d04 fix: use esp_http_client for KOSync to prevent TLS OOM on ESP32-C3 (#1381)
## Summary

* **What is the goal of this PR?** Fix KOReader sync failing on HTTPS
servers due to TLS out-of-memory on ESP32-C3
* **What changes are included?**
- Replace `WiFiClientSecure`/`HTTPClient` with `esp_http_client`
(ESP-IDF native API) for all KOSync HTTP requests
- Use 2KB TLS buffers instead of the default 16KB — KOSync payloads are
tiny JSON (<1KB), so this is more than sufficient
- Use `esp_crt_bundle_attach` for proper TLS certificate verification
(replaces `setInsecure()`)
- Strip trailing slashes from server URL to prevent double-slash in API
paths (e.g. `https://server.com//users/auth`)
  - Add `lastHttpCode` static field for diagnostics
  - Add free heap logging to help debug memory issues

### Problem

The ESP32-C3 has ~46KB free heap after WiFi is initialized.
`WiFiClientSecure` allocates 16KB for TLS RX + 16KB for TLS TX = 32KB
just for the TLS buffers, leaving almost no room for the actual TLS
handshake (which needs additional dynamic allocations). This causes
KOReader sync to:

1. Fail silently with network errors on HTTPS servers (including the
default `sync.koreader.rocks`)
2. Occasionally crash with heap exhaustion

### Solution

`esp_http_client` (the ESP-IDF native HTTP client) allows configuring
`buffer_size` and `buffer_size_tx` independently. Setting both to 2KB
(total 4KB) leaves plenty of heap for the TLS handshake while still
being sufficient for KOSync's small JSON payloads.

This also fixes the `setInsecure()` anti-pattern —
`esp_crt_bundle_attach` provides proper certificate verification using
the ESP-IDF's built-in CA bundle, so credentials and reading history are
no longer sent over unverified TLS connections.

### Files changed

| File | Change |
|------|--------|
| `lib/KOReaderSync/KOReaderSyncClient.cpp` | Replace
WiFiClientSecure/HTTPClient with esp_http_client; add ResponseBuffer,
base64 encoder, createClient helper |
| `lib/KOReaderSync/KOReaderSyncClient.h` | Add `lastHttpCode` static
field |
| `lib/KOReaderSync/KOReaderCredentialStore.cpp` | Strip trailing
slashes from base URL |

## Additional Context

Tested on a CrossPoint X4 (ESP32-C3 with 4MB flash). Before this change,
KOSync auth to `sync.koreader.rocks` (HTTPS) would fail ~80% of the
time. After: works reliably.

The `base64Encode` helper is needed because `esp_http_client` doesn't
have a built-in `setAuthorization()` method like `HTTPClient` does. This
is used for the HTTP Basic Auth header required by Calibre-Web-Automated
KOSync servers.

Fixes #581

spfenwick bc9651b664 fix: use same file name as KOReader for OPDS downloads (#1286)
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.

Rob Hooperandrhoopr 741dd89ac1 fix: cap per-side horizontal CSS inset at 2em (#1694)
## Summary

- **What is the goal of this PR?** Fix chapter-opener text collapsing to
1-2 words per line in EPUBs that apply large em-based horizontal CSS
insets.
- **What changes are included?** Caps `marginLeft`, `marginRight`,
`paddingLeft`, and `paddingRight` at 2em in `BlockStyle::fromCssStyle`
(`lib/Epub/Epub/blocks/BlockStyle.h`). Vertical margins/padding are
unchanged - the bug is horizontal-only.

## Additional Context

**Repro:** *Mother Night* by Kurt Vonnegut, Chapter 21 ("My best
friend..."). The chapter-opening element's embedded CSS sets a large
horizontal inset.

- Settings: Embedded Style = On, Justify alignment (default).
- Before: 1-2 words per line with a visible river between them.
- After: body text fills the usable page width like every other
paragraph.

**Why the clamp lives in `fromCssStyle`:** This is the single point
where CSS lengths resolve to pixels, so clamping here keeps both
`effectiveWidth` call sites in `ChapterHtmlSlimParser` (`:1131-1133`
makePages, `:841-844` long-block split) consistent with the
`leftInset()` xOffset. A width-only clamp at either call site would
leave text pushed right by a large xOffset.

**Test plan:**
- [x] Flashed to Xteink X4. Chapter 21 of *Mother Night* renders
normally with Embedded Style on.
- Users with cached layouts of affected books need to delete
`.crosspoint/epub_<hash>/sections/` (or the whole `.crosspoint/`) on the
SD card to pick up the fix.

**Before / After:**

pablohc 907e14da28 fix: pressing space barely moves input cursor (#1729) (#1733)
## Summary

* **What is the goal of this PR?** 
Fix the visual keyboard cursor not advancing when typing a space. Typing
one space leaves the cursor at position 0; typing two spaces advances it
only by one space width. This affects all input types except URL.
* **What changes are included?** 
Replace `getTextWidth()` with `getTextAdvanceX()` in four locations
within `KeyboardEntryActivity::render()` for cursor positioning and
line-wrapping calculations.

## Additional Context

* **Root cause**: `getTextWidth()` returns the bounding-box width of the
drawn glyphs. The space glyph has `width=0` and `height=0` (it's
invisible), so `getTextWidth(" ") == 0`. The trailing `advanceX` of the
last character is only flushed when the *next* character is processed,
so a string ending in space reports zero width. `getTextAdvanceX()`
correctly includes the final glyph's advance, matching how `drawText()`
actually positions characters.

Arthur TazhitdinovandCopilot 1cf2239742 feat: Support for multiple OPDS servers (#1209)
## 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.

Pietro CampagnanoandClaude Sonnet 4.6 867fb7cbe2 style: unify page headers across web UI (#1702)
## Summary

* **Goal**: Align `FilesPage` and `SettingsPage` headers with the
existing `HomePage` pattern.
* **Changes**:
- Added `<h1>📚 CrossPoint Reader</h1>` at the top of `<body>` on both
pages.
- Demoted the page-specific `📁 File Manager` heading on `FilesPage` from
`<h1>` to `<h2>` (inside `.page-header`), so every page has a single
`<h1>` — the app name.
- Moved the accent-colored `border-bottom` from `.page-header` to `h1`,
matching the HomePage CSS.

All three pages now share the same top structure:
`<h1>CrossPoint Reader</h1>` → nav links → page content.

## Screenshots

### Home

**Before and after is the same**

## Additional Context

* Pure markup + CSS, no JavaScript or behavioral changes.
* Improves HTML semantics (single `<h1>` per page, referring to the
app).
* No new CSS duplication introduced — borrows existing styling from
HomePage.

CSCMe 8154f88dbe fix: Erroneous navigation with long filenames in footnote links (#1723)
## Summary

* **What is the goal of this PR?** 
* Increase the allowed link length for footnotes
* **What changes are included?** 
* Un-magic-numbers parts of the footnote parser
* Increases max href length

## Additional Context

* Additional RAM usage was not noticable to me, worst case 16 * 128 * 2
= 4KB instead of previously 16 * 88 * 2 ~ 2.8KB, see #1031
* Motivation: My book navigated me to the start of the footnote chapter,
which required manual navigating for every footnote due to ungodly file
name choices which pushed the required href length to 72, which caused
truncating, which caused Crosspoint to not find the anchor (Sacred and
Terrible Air, available via reddit)

Pietro Campagnano 9dab5f471b style: put page name first in browser titles (#1703)
## Summary

* **Goal**: Make browser tab titles, bookmarks, and history entries
distinguishable across pages (including individual folders in the File
Manager).
* **Changes**:
- Reordered `<title>` so the page name comes first, followed by
`CrossPoint Reader`. Browser tabs usually truncate titles from the
right, and bookmark/history lists are sorted alphabetically by title —
putting the differentiating part first keeps it visible in both cases,
instead of every entry starting with `CrossPoint Reader - …`.
- On `FilesPage`, added a small JS hook that updates `document.title`
with the current subfolder leaf when a `path` query parameter is present
— previously all folders shared the same title.

| URL | Title before | Title after |
|-----|--------------|-------------|
| `/` | `CrossPoint Reader` | `CrossPoint Reader` _(unchanged)_ |
| `/settings` | `CrossPoint Reader - Settings` | `Settings - CrossPoint
Reader` |
| `/files` | `CrossPoint Reader - Files` | `Files - CrossPoint Reader` |
| `/files?path=/Books` | `CrossPoint Reader - Files` | `Books - Files -
CrossPoint Reader` |
| `/files?path=/Books/Fantasy` | `CrossPoint Reader - Files` | `Fantasy
- Files - CrossPoint Reader` |

## Additional Context

* Pure client-side change: `<title>` tags plus ~3 lines of JavaScript on
FilesPage. No network, behavior, or memory impact.
* The static `<title>` tag remains as a fallback if JS fails.
* `HomePage` title left as-is since the app name alone is the standard
convention for a root/home page.

mvidelatraduc ce22deab7c chore: Update spanish.yaml (#1717)
## 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.

Pietro CampagnanoandClaude Sonnet 4.6 e28918b24d fix: pluralize folder/file counts correctly in file list summary (#1701)
## Summary

* **Goal**: Fix incorrect pluralization in the file manager web UI
summary line.
* **Changes**: `FilesPage.html` always rendered the plural forms
("folders"/"files") regardless of count. The summary now selects
singular or plural based on each count.

Example:
- Before: `1 folders, 1 files, 12 KB`
- After: `1 folder, 1 file, 12 KB`

## Additional Context

* Cosmetic-only fix — no behavior, performance, or memory impact.
* Change is fully client-side (JavaScript inside a single HTML
template).
* English-only; web UI localization is out of scope here.

Brandon PhilipsandClaude Sonnet 4.6 c0ee096841 fix: relative opds paths and query param with copyparty (#1535)
## Summary

* **What is the goal of this PR?**

This PR fixes bugs when using Copyparty as an OPDS server. 

https://github.com/9001/copyparty?tab=readme-ov-file#opds-feeds

OPDS uses a query parameter `?opds` to differentiate between HTML
requests and OPDS requests for the same path. It also uses relative
paths in the responses instead of full paths. Crosspoint didn't handle
these two cases.

* **What changes are included?**

Fixes to the two issues above.

## Additional Context

* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks,
  specific areas to focus on).

Here is some example XML from my Copyparty instance:

- **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

Zach Nelson 64f5ef018a feat: Support for proportional numeral spacing (#1414)
## Summary

**What is the goal of this PR?**

Reading a book with frequent numbers, I noticed that the spacing between
numeral glyphs was strangely large. This was because Bookerly and Noto
Sans default to tabular figures, where every digit gets an identical
advance width. This is designed for column alignment in spreadsheets,
but in rendering prose it produces visually wide gaps between digits.

This change adds a `--pnum` flag to fontconvert.py that applies the
font's OpenType `pnum` (proportional numerals) feature during
conversion. When active, the converter:
- Parses the GSUB table for pnum SingleSubst lookups
- Resolves substitute glyph indices via fonttools' glyph order
- Loads the proportional alternate glyphs instead of the tabular
defaults
- Includes substitute glyph names in kern pair extraction, so kerning
data that references proportional alternates is captured

Bookerly's proportional alternates also carry digit-digit and
digit-punctuation kerning that the tabular glyphs lack (e.g., at 16pt
7->4 at -1.69px, 7->. at -2.31px, 7->1 at +1.00px).

Noto Sans gains proportional advances but no new kerning (its
proportional glyphs have no kern class data in the font).

OpenDyslexic is unaffected. Its `cmap` already points to proportional
glyphs, so `--pnum` is a no-op. `--pnum` is intentionally omitted from
OpenDyslexic in the build script for deliberately uniform digit spacing
as an accessibility choice.

UI fonts (Ubuntu, notosans_8) also omit `--pnum` to preserve tabular
alignment for page numbers, battery percentages, etc.

## 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] Lyra Theme on X4
- [ ] Lyra Extended Theme on X3
- [x] Lyra Extended Theme on X4

### 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
- [x] `"lowercase"` shown when shift ON
- [x] `"secondary char"` shown for InputType::Url

### 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
