/* Console color themes — a personal, per-browser preference for the studio's
   own UI chrome (see theme-picker in studio.js), completely separate from
   Brand tab's background/overlay controls, which style the actual broadcast
   output. --text/--text-dim/--live/--ok stay fixed across every theme: the
   first two read fine against any sufficiently dark background regardless of
   hue, and the last two are semantic (live/recording, success) rather than
   decorative, so recoloring them per-theme would undermine the one thing
   they're for — staying instantly recognizable no matter what else changes. */
