Review follow-up:
- Arrow keys, Home and End now check the settings radio they reach, as a
native radio group does (the directive clicks it, so the template's
handler applies the choice); an option the engine already reports as
checked is not applied again.
- With subtitles on but no track marked selected yet (the engine can
report the switch before the track list), the subtitle chip reads and
announces "On" (new SUBTITLES_ON key, 19 locales) instead of "Off".
- The swatch row has 4px padding on every side, so the outer focus ring
is not clipped at the scroll edge of the panel body.
