   Now Playing, technique panels (Tri-Beam / Solar Flare /
   Dodon Ray / Multi-Form / Four Witches), Mimicry, LionDavid,
   mixes, source rows, onboarding.

   SAFETY (Solar Flare): the glow layer, its gentle 4s pulse,
   the photosensitivity warning modal, the brightness control,
   reduced-motion support, and default-OFF behavior are owned by
   js/solarflare.js and are NOT restyled here. This file only
   restyles the .solar-card control panel. No strobing, ever.
