The watch recolors to the active provider's brand, live, and it's cheap to add
more providers later.
Firmware:
- theme.h: expose THEME_ACCENT_HEX; ui.cpp: COL_ACCENT becomes a runtime
lv_color_t backed by a shared style (s_accent_style). Static accent widgets
(launcher tile icons, usage status line, session tokens) attach the shared
style, so ui_set_theme() recolors them instantly via lv_obj_report_style_change
— no widget tracking, no recreation.
- ui_set_theme(pv, accent_rgb): swaps the accent + a small logo table keyed by
provider id (fallback to the Claude mark until a provider ships a logo). Change-
guarded, so the ~3s payload cadence doesn't churn.
- main.cpp: parse "pv" (id) + "ac" (0xRRGGBB) from the payload and apply.
- Adding a provider needs zero firmware color edits (accent is data-driven) and
at most one logo-table row.
Daemon: push "ac" = active provider's brand accent alongside "pv".
Test fix: test_providers used asyncio.run(), which closed the suite's shared
event loop and broke every later get_event_loop() test (Py3.13) — mirror the
repo's _run() helper instead.
Verified on the 2.06: forcing an OpenAI-green theme recolored the live launcher
icons (report_style_change path). 216 builds clean; daemon suite 94 passed.
