The daemon reads the Windows "now playing" media session (WinRT SMTC) and
adds np/nt/na to the BLE payload; the watch shows a play/pause glyph, a
scrolling title, artist and status. Best-effort and token-independent, so
it works even when the rate-limit data is unavailable.
Cyrillic titles: Styrene B has no Cyrillic glyphs, so the title/artist use
new composite fonts (font_styrene_cyr_{28,20}) — Latin from Styrene B,
Cyrillic + typographic punctuation from Montserrat, merged by lv_font_conv.
Latin titles stay on-brand; only Cyrillic falls back to Montserrat.
- daemon: read_now_playing() via winrt-Windows.Media.Control (lazy import,
never raises; PLAYING->1, PAUSED->2, else 0; title/artist truncated,
empty fields omitted)
- firmware: UsageData np_state/np_title/np_artist + parser; the real Now
Playing screen replaces the shared stub (SCREEN_NOWPLAYING)
- fonts: assets/Montserrat-Medium.ttf, font_styrene_cyr_{28,20}.c
- tools: patch_lvgl9_font.py (automates the 4 LVGL 9 font patches),
screenshot_win.py (Windows serial screenshot via pyserial + Pillow)
- README: document Cyrillic composite font generation
Verified on hardware (waveshare_amoled_206): idle state, a live Latin
title (scrolling), and Cyrillic (Prohozhdenie / Dunduk) all render.

"""Patch lv_font_conv output for LVGL 9.
|
|
|
|
`lv_font_conv` emits font .c files wrapped in `#if LVGL_VERSION_MAJOR` guards and
|
|
(for v8) a `.cache` field. On LVGL 9 the project wants the plain, unguarded struct
|
|
with `.release_glyph` / `.kerning` / `.static_bitmap` present (see the "LVGL 9 font
|
|
patching" note in README.md). Without this the font compiles but renders invisible.
|
|
|
|
Usage:
|
|
python tools/patch_lvgl9_font.py firmware/src/font_foo.c [more.c ...]
|
|
|
|
Idempotent: running it on an already-patched file is a no-op.
