/* Pick Winner — How It Works
 * ==========================================================
 *
 * PR-1: dark cinematic shell + 10 act scaffolds. Each act is a
 * full-viewport dark section with room for GSAP ScrollTrigger
 * to pin + animate in PR-2. This CSS establishes the resting
 * state and typography; motion / reveal timing lives in JS.
 *
 * Design palette locked to the site's existing cinematic
 * language (Papers + Pinsticker):
 *   ink       #0b1220
 *   ink-2     #0f1826
 *   gold      #d4af37
 *   gold-mute rgba(212,175,55, .55)
 *   text      #f0e8d5
 *   text-mute rgba(240,232,213, .68)
 *   green     #4ade80  (validation ticks)
 *   red       #ef4444  (elimination)
