   /speaker-cleaner - Speaker Cleaner & Water Eject

   A dark stage in the family of /sound-test and /phone-speaker-test,
   over a light control panel. --lvl (0..1), --jx and --jy are written
   by speaker-cleaner/page.js from the AnalyserNode on the engine's
   final output, so the cone, the grille glow and the halo follow the
   real pulses - not a decorative loop. Everything is scoped under
   .sc / .sc-page.

   Brand colours come from the A-to-Z tokens (device-health.css loads
   first); each var() carries the same value as its fallback, so there
   is no second palette. NOTHING HERE REPORTS A RESULT BY COLOUR ALONE -
   every verdict carries its words.
