Since 2.10.0 the app opens on a Flutter-owned startup frame, and that frame
paints an opaque themed Scaffold before any preference is readable. Its
themeMode defaults to system, so the theme comes from platform brightness --
and a TV has no system dark-mode toggle, so Fire TV and Shield report light.
The result was a near-white #F7F7F8 sheet held for the whole gate, from
prefs through Sentry to the database open, over an Android window the
television resource qualifier had already painted black. Before 2.10.0 the
gate ran ahead of runApp and no Flutter frame existed to cover it.
Nothing in the loading frame is worth covering the launch screen for. Android
composites Flutter in TransparencyMode.transparent over a window whose colour
MainActivity already restored from plezy_prefs, so the loading Scaffold is
transparent there and the launch screen carries the launch. Every other
platform composites opaquely with nothing behind Flutter, so they keep
painting their own background.
The spinner and the failure screen still need a colour, and platform
brightness is the wrong one for exactly the devices this bug is about, so the
startup frames now adopt the persisted theme once it can be read. TV
detection has to run before that read: the theme_mode default is TV-aware and
isTVSync answers false until its singleton exists, which would resolve a
fresh Android TV install to the light theme. Both singletons are memoised and
awaited again by the gate. The read is best-effort -- an unreadable store is
the gate's failure to report, not this path's -- and it also stops a startup
failure from rendering as a full-screen white error page on a TV.
darkThemeFor and materialThemeModeFor move onto ThemeProvider so the startup
frames and the provider resolve OLED from one mapping rather than two.
Verified on an Android TV emulator in television/notnight mode, clean install,
cold start: peak frame luma 228 for 78 frames before, 0 frames above 120
after, and the same on a returning launch.

Focus chrome was implemented twice, once in the focusable wrapper and once
in the focus builders; both now go through FocusChrome. TvColorPicker's
channel row was a copy of TvNumberSpinner and is now that widget in compact
density.
Also trims unused helpers and fields and simplifies the Jellyfin browse
paths.
