/* A Tiny Rush — the whole look. The UI is light floating IN the tunnel, not
   a menu skinned over it: no boxed cards, no borders-around-everything. The
   idle scene stays visible behind every screen; type, glow and scrims do all
   the work.

   DOM contract: index.html provides #game / #flash / #ui; ui.js builds all
   menu/HUD DOM inside #ui; effects.js animates #flash inline.

   TYPE SYSTEM — one face stack (--font), ALL-CAPS hierarchy, five tiers:
     T1 MONUMENT   900 · ls 0.04-0.12em · white→hue gradient or white core,
                   triple hue glow. Titles: RUSH, level names, CLEAR, PAUSED.
     T2 IMPERATIVE 900 · ls 0.28-0.32em · white core + hue halo, breathing
                   glow, flanked by light beams. THE one action per screen.
     T3 KICKER     700 · ls 0.4-0.55em · accent ink + soft hue glow. Labels
                   above/below titles (A TINY, LEVEL 03, BREAKS).
     T4 SATELLITE  700 · 11px · ls 0.28em · dim ink, hover→white. Quiet
                   secondary actions orbiting the imperative.
     T5 WHISPER    700 · 9-11px · ls 0.25-0.3em · faint ink. Hints, dismiss
                   lines, key-cap rows.

   SCRIM TIERS — every floating text must read on the brightest tunnel frame:
     S1 HARD  text-shadow: 0 2px 4px #000e, 0 0 16px #000c   (HUD numerals)
     S2 SOFT  text-shadow: 0 1px 3px #000c, 0 0 12px #0009   (labels, hints)
     S3 POOL  ::before radial ink pool behind a floating cluster — light
              falloff, never a rectangle.

   MOTION — entrances/exits are light-based: opacity + blur + scale/rise,
   150-250ms (matIn / matUp). Idle life: beaconPulse (the imperative
   breathes). All killed under prefers-reduced-motion. */
