- Add lib/GxEPD2-patch/src/GxEPD2_BW.h: local patched copy of GxEPD2_BW.h
that exposes getBuffer()/getBufferSize() under ENABLE_SCREENSHOT guard.
Include guard (_GxEPD2_BW_H_) prevents double-inclusion of the installed
library version.
- GxEPDDisplay.h: use patched header via relative include when
ENABLE_SCREENSHOT so the patch takes precedence over the installed lib
(PlatformIO adds library paths before -I build_flags).
- DisplayDriver.h: add virtual getBuffer()/getBufferSize()/getDisplayType()
defaults (nullptr/0/0) under ENABLE_SCREENSHOT.
- SH1106Display.h / SSD1306Display.h / GxEPDDisplay.h: add concrete overrides;
getDisplayType() returns 0 (OLED) or 1 (e-ink).
- MyMesh.cpp/h: replace fragile C-cast with virtual dispatch in
handleScreenshotRequest(); extend 5-byte header to 6 bytes by appending
display_type so the host tool can decode the correct pixel layout.
- tools/screenshot.py: parse 6-byte header; add eink_buffer_to_image()
that decodes the row-major MSB-first GxEPD2 buffer with DISPLAY_ROTATION=1
(phys_x = 127-ly, phys_y = lx); dispatch on display_type.
- variants/wio-tracker-l1-eink/platformio.ini: add
[env:WioTrackerL1Eink_companion_dual_dev] with ENABLE_SCREENSHOT.
- variants/wio-tracker-l1/platformio.ini: unchanged (OLED env already exists).
Builds verified: WioTrackerL1Eink_companion_dual_dev SUCCESS,
WioTrackerL1Eink_companion_radio_ble SUCCESS (unaffected).

In GxEPDDisplay::print(), the 0xDB fallback block was drawn at
cy - 8*scale, which assumed the Lemon baseline convention
(cy = original_y + 8*scale). For the default GFX font fontAscender
returns 0, so cy = original_y (top of cell) — the block landed
16 px above the character on e-ink (scale=2).
Fix: draw at cy (top of cell) for the non-Lemon path.
Also remove the unused forceNextRefreshFull() virtual from
DisplayDriver — it was added based on a wrong hypothesis (partial
refresh ghosting) and was never wired into endFrame().

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.

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().

- 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

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.

Adds Settings > Display > Rotation (0°/90°/180°/270°) that persists to
NodePrefs and is applied on startup. Falls back to compile-time
DISPLAY_ROTATION when the field is missing from an older prefs file.

- 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

Adds ð/Ð (eth), þ/Þ (thorn) for Icelandic, and ţ/Ţ (t with cedilla)
for legacy-encoded Romanian text.

Adds háček and other Czech/Slovak characters (č š ž ř ě ů ď ť ň ľ ĺ ŕ)
to the UTF-8 transliteration table so they display as ASCII letters
instead of █ blocks.

Names printed via drawTextEllipsized (contacts, senders) bypassed
translateUTF8ToBlocks, causing raw UTF-8 bytes to render as garbage
on the Adafruit font. Now transliteration happens inside the method.

Replaces the block-character fallback with proper transliteration for
Polish (ą→a, ć→c, ę→e, ł→l, ń→n, ó→o, ś→s, ź→z, ż→z), German (ä ö ü ß),
and common French/Spanish/Portuguese accents. Unknown codepoints fall back
to '?' instead of █.
