/* ==========================================
   LiveTV — residual styles
   Everything visual now lives in Tailwind (utility classes + the
   `tailwind.config` and `@layer` blocks inside index.html). This file
   keeps only the few rules Tailwind utilities can't express cleanly:
   the ambilight canvas/backdrop, the JS-driven play-flash animation,
   the theater-mode dim overlay, and the custom range-slider thumb.
