Re-ran test/servicios/navegacion_auto_test.dart (129 tests) unmodified —
all pass. git diff for lib/servicios/navegacion_auto.dart is empty; this
commit makes zero code changes.
Formally closes A1-A5 from the proposal's Android Auto surface review. The
app uses the classic MediaBrowserService model (automotive_app_desc.xml,
no androidx.car.app); Android Auto's system templates render everything,
and the only controllable surface is MediaItem metadata, which already
matches the redesign's intent. A4's waveform visualization is confirmed
non-implementable on this platform — MediaBrowserService cannot render
custom widgets, only system-templated browse/playback UI.
