/* ============================================================
   Visual Metronome — /apps/visual_metronome/
   A dark stage that pulses on the beat, sequencer grid lines and big
   tempo numerals; the light theme is a bright rehearsal room with the
   same rhythm. Palette from the app's own theme (lib/core/theme.dart
   and ui/rhythm/scene_palette.dart): graphite stage, chalk lettering,
   brass for the accented beat, ice for every other beat.
   Type: Unbounded (display + numerals), Outfit (reading).
