/* ---------------------------------------------------------------------------
   Fizz Liquids Empire — visual theme
   All colors, spacing and radii live in :root; components only consume the
   variables, so the whole look can be retuned in one place.

   Performance rule: this stylesheet is deliberately static — no animations,
   no transitions, no backdrop-filter. render() runs every tick, and every
   frame the browser repaints whatever changed; animated or blurred styles
   turn that 1 Hz refresh into constant compositing work. Instant state
   changes (class swaps, opacity flips) keep the tick cheap and the UI
   responsive, which matters more than flourish in a 1-tick-per-second game.
