Framework for upcoming variant-specific PRs that add LED feedback during boot. The hook gives users visual cues that the device is busy and
shouldn't be interacted with until startup completes.
Match the rest of the file's defaults; constructor body no longer
re-initialises a field that the in-class initializer already set.

Eight screens repeated the same if/else block to invert the row
background for selected items. Add DisplayDriver::drawSelectionRow that
sets LIGHT, optionally fills the rect, and leaves the colour as DARK
when sel (so the caller's text renders inverted). 61 lines removed
across SettingsScreen, KeyboardWidget (cells + special row), ToolsScreen,
DashboardConfigScreen, BotScreen, RingtoneEditorScreen (note slots +
menu), NearbyScreen, QuickMsgScreen (4 list views).
Card-style rows (QuickMsg hist, NearbyScreen discover, RingtoneEditor
notes display) keep their original drawRect/partial-fill outline for
unselected — they don't match the simple-invert pattern.

Three copies of the same routine: DisplayDriver::decodeCodepoint (added
in the FullscreenMsgView wrap fix) plus per-driver duplicates in
SH1106Display and GxEPDDisplay. Consolidate on DisplayDriver and have
translateUTF8Static also route through it instead of its own inline
decoder. Net: 63 lines removed, single source of truth.

The wrap loop used to memcpy a growing substring and call getTextWidth
on it for every appended codepoint — O(n²) UTF-8 decoding with Lemon
font, ~5-20 ms on a full e-ink redraw of a long message.
Add DisplayDriver::getCodepointWidth(cp) (default: build a UTF-8 buffer
and forward to getTextWidth) plus DisplayDriver::decodeCodepoint() as
the shared UTF-8 walker. Override getCodepointWidth in GxEPDDisplay
(direct lemonXAdvance for Lemon size 1) and SH1106Display (lemonXAdvance
for Lemon, fixed 6*sz for built-in font). FullscreenMsgView now walks
codepoints once and sums widths incrementally.

Old 80+ case switch generated a jump table around ~600-1200 B of flash;
new layout is two parallel static-const arrays (uint16 codepoint + char
ascii, 144 entries each = 432 B) and a 5-line bsearch loop. Same input
range, same output, faster lookup (~log2(144) ≈ 7 compares vs jump-table
indirection + bounds check).
Adds a static_assert that the two arrays stay in sync.

Per-char recomputation of (width() >= height() ? 2 : 1) in drawLemonChar
and lemonXAdvance is now passed in by the caller. print() and
getTextWidth() compute scale() once and feed it to every glyph. All
other callers in the file route through the helper for consistency.

For a 140-byte channel msg with a 64-byte trigger, the old loop did
~8960 tolower() calls per inbound message; now it's 140 tolower calls
plus one strstr.
perf(buzzer): skip nRF52 STOPPED wait when PWM was not running
TASKS_STOP on a disabled PWM never fires EVENTS_STOPPED, so the wait
always timed out at 2 ms. Gating on _pwm_on removes the wait on the
first note of a melody and after pauses, where there's nothing to wait
for.

setTextSize(2/3) switches GFX to non-Lemon fonts (built-in scaled or
FreeSans18pt). The Lemon path bypassed GFX entirely and rendered glyphs
at size 1 scale, shrinking splash version and clock when Lemon font
was active.
Refresh CODE_REVIEW.md: remove resolved issues (signed-int timing vars,
abs() no-op, XBM CRC, loadPrefs nesting, lock-screen LPP thrash, reply
prefix raw UTF-8), add new findings (upstream-merge surface, virtual
width()/height() per glyph, page_order sentinel), list enhancement
ideas.

The placeholder rectangle for codepoints outside U+0020-U+04FF was drawn
1 scale unit too low (y-7*sc instead of y-8*sc relative to the GFX
baseline), causing it to sit below full-height glyphs.

Adafruit GFX write(uint8_t) treats each byte as a glyph index and cannot
decode multi-byte UTF-8 sequences, so Cyrillic and other non-ASCII chars
were rendered as garbage even with the Lemon font selected.
Add decodeUtf8 + drawLemonChar + lemonXAdvance to GxEPDDisplay, mirroring
the existing SH1106Display implementation. Override print() for Lemon mode
to decode UTF-8 codepoints and draw each glyph directly; override
getTextWidth() to sum per-codepoint advances.

drawTextCentered/Left/Right/Ellipsized all call translateUTF8ToBlocks
before passing text to print(), which converted Cyrillic (and other
Unicode) to block characters even when the Lemon font was selected.
Override translateUTF8ToBlocks in GxEPDDisplay to skip conversion when
_use_lemon is true — the Lemon/GFX font handles UTF-8 natively.

Add "Full rfsh" setting (e-ink only) with options off/5/10/20/30
partial refreshes between full refreshes. Prevents ghosting on panels
that accumulate artifacts after many partial updates.
GxEPDDisplay counts partial refreshes and calls display.display(false)
every N frames when the interval is set. Persisted in DataStore and
applied at startup via applyFullRefreshInterval().

Add NodePrefs::joystick_rotation (0-3 steps CW), persisted in DataStore
alongside display_rotation. rotateJoystickKey() now takes a runtime rot
parameter instead of compile-time JOYSTICK_ROTATION macro. UITask::loop()
reads joystick_rotation from NodePrefs each frame. Settings screen exposes
"Joystick" rotation item on any build with UI_HAS_JOYSTICK. JOYSTICK_ROTATION
macro still works as compile-time default for legacy/non-prefs builds.

- GxEPDDisplay::print() renders '\xDB' as filled rect for Lemon font,
matching OLED Lemon block behavior
- Remove translateUTF8ToBlocks override (base class passthrough sufficient)
- transliterateCodepoint fallback changed '?' → '\xDB' for consistency
- drawTextCentered/Right/LeftAlign now call translateUTF8ToBlocks
- isLemonFont() added to DisplayDriver, SH1106Display, GxEPDDisplay
- isLandscape() guarded by EINK_DISPLAY_MODEL to distinguish OLED vs e-ink
- ind_h trims indicator box height only for Lemon font
- getTextWidth disables wrap before getTextBounds, restores after
- QuickMsgScreen: tighter hist_item padding; 2 messages visible with Lemon
- Hibernate hint fits on one line when width allows, splits otherwise
- BLE PIN page shows toggle hint on landscape e-ink
- Remove unused muted_icon bitmap
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- GxEPDDisplay: fontAscender only applies to sz=1 with Lemon; sz=2 (NULL font)
was incorrectly getting a 16px cursor offset, causing clock text to render
16px lower than expected and overlap the date line
- KeyboardWidget: compute cell_h from available screen height instead of lh+1;
tighten sep_y to lh so the grid fits within 122px even with Lemon font (lh=20)
- SettingsScreen renderBar: constrain box size to available width so the 5th
buzzer-volume square doesn't overflow past the right edge with Lemon font
- NearbyScreen discover detail: manually truncate b64 public key by charWidth
to guarantee one-line rendering; use dynamic step = (height-hdr)/5 so
Status line doesn't fall off the bottom of the screen
- NearbyScreen contacts detail: merge dist+az into one line and use dynamic
step to fit 5 lines within the display; removes the off-screen Seen: row
- AutoAdvertScreen: replace lineStep() gap before hints with 4px fixed gap
so both hint lines fit within the display with large fonts

Add lineStep(), headerH(), listStart(), listVisible(), valCol() to
DisplayDriver so layout derives from getLineHeight() instead of fixed
OLED constants. Refactor all screens (SettingsScreen, NearbyScreen,
FullscreenMsgView, QuickMsgScreen, BotScreen, DashboardConfigScreen,
AutoAdvertScreen, RingtoneEditorScreen) and all HomeScreen pages plus
the lock screen and splash screen in UITask.cpp.
On OLED (lh=8) positions are unchanged; on landscape e-ink (lh=16) all
text and widgets now scale correctly to the 250×122 display.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Portrait mode (122px wide) matches the OLED's ~21 chars/line with a 1× font.
Landscape mode (250px wide) was using the same small 6×8 font, leaving text
physically tiny and the wide display underutilised.
Size 1 now scales by orientation: 1× (6×8 / Lemon 5×10) in portrait,
2× (12×16 / Lemon 10×20) in landscape. Size 2 stays at 12×16 and size 3
at FreeSans18pt in both orientations — their layout Y-positions are hardcoded
so they cannot be scaled without a full layout refactor.
fontAscender() updated to accept a scale parameter; Lemon ascender becomes
8×scale (8px portrait, 16px landscape) to keep top-of-cell coordinate
semantics consistent with the rest of the UI code.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Layout fix: GxEPDDisplay was using proportional GFX fonts (FreeSans9pt/12pt)
for sizes 1 and 2, giving lineHeight=16/20 instead of the 8/16 the UI layout
expects (designed for the OLED's bitmap font). Replaced with the GFX built-in
6×8 bitmap font (size 1) and its 2× scaled variant 12×16 (size 2). Size 3
keeps FreeSans18pt for large headings. fontAscender updated accordingly:
built-in font cursor is top-left (offset=0), Lemon GFX font adds 8px,
only FreeSans18pt still adds 26px.
Lemon font: LemonFont.h already stores the font in GFXfont format, so
GxEPDDisplay can use it directly via display.setFont(&Lemon). Added
_use_lemon flag, setLemonFont() override, and size-1 font selection in
setTextSize()/startFrame(). Adafruit GFX handles UTF-8 decoding for GFX
fonts, so Unicode characters (Cyrillic etc.) render correctly. The FONT
setting in SettingsScreen now works on e-ink the same as on OLED.

Adds Settings > Display > Rotation (0°/90°/180°/270°) that persists to

- Remove fixed 128×128 virtual space and scaling; use 1:1 pixel mapping
- Display dimensions derived from panel native size + DISPLAY_ROTATION
- setCursor compensates for GFX font baseline offset (ascender per font size)
- Add getLineHeight() / getCharWidth() overrides for FreeSans fonts
- New envs: landscape (250×122) and portrait (122×250), BLE and dual variants
- Integrate all wio-tracker-l1-improvements features into e-ink build
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Add Lemon font (LemonFont.h, LemonIcons.h) to the standard build
alongside the Adafruit built-in font; ~101 KB added to flash
- SH1106Display: add _use_lemon flag + setLemonFont(bool) to switch
at runtime; print() and getTextWidth() use Lemon path when active;
translateUTF8ToBlocks() passes UTF-8 through unchanged (Lemon supports
full Unicode U+0020-U+04FF) vs transliterating for the default font
- DisplayDriver: add getCharWidth()/getLineHeight() virtuals (defaults 6/8);
SH1106Display returns 5/9 for Lemon, 6/8 for default; add setLemonFont()
no-op virtual; fix orphaned UTF-8 leading byte in drawTextEllipsized
- FullscreenMsgView: replace fixed-char-count word-wrap with pixel-accurate
wrap using display.getTextWidth(); use getLineHeight() for spacing so
Lemon (9 px) and default (8 px) both render correctly
- NodePrefs: add use_lemon_font field (0=default, 1=Lemon)
- SettingsScreen: add "Font" item in Display section (Default / Lemon),
calls UITask::applyFont() on change
- UITask: add applyFont() that calls display->setLemonFont(use_lemon_font);
called at startup (begin()) and when the setting changes

Extract the inline cursor-walk in handleRegionCmd into file-local
helpers (skipSpaces, rtrimSpaces, takeToken, splitNameJump,
processRegionDefSegment), grouped immediately above the consumer.
Behavior is identical; addresses PR #2540 review feedback on
readability.
Tighten the region def docs: collapse five Note callouts into three
grouped paragraphs (Behavior / Existing regions / Limits), add a
case-sensitivity caveat plus an error example, note the cursor reset
between split commands, and use generic placeholder names.

- Use inverted PWM polarity (0x8000) with PCT {2,5,12,25,50} giving
~6-8 dB perceptual steps (-24/-16/-9/-3/0 dB) vs the original
uneven steps where levels 4 and 5 were only 1 dB apart
- Guard against cmp=0 truncation in both _nrfStartPwm and applyVolume:
at level 1 with high notes (freq > ~2.5 kHz) integer math gives
cmp=0 which with inverted polarity means 100% HIGH → complete silence
- Change volume preview note from C5 (523 Hz) to C6 (1047 Hz) to better
match the piezo resonant frequency range and actual notification sounds
