/*
 * The Fone Shop — Design System
 * ------------------------------
 * Cinematic, tungsten-warm, black-on-black with Apple Dynamic Orange (#FF6B1A).
 * Source of truth: anvul-platform/packages/core/styles/tokens.css +
 *                  anvul-platform/apps/fone-shop/app/globals.css
 *
 * Non-negotiables (CLAUDE §4 + CINEMATIC):
 *   - Pure black #000 backdrop. Tungsten-warm crush. NO light/dark alternation.
 *   - Accent: Apple Dynamic Orange #FF6B1A. Black text on orange (AAA 8.12:1).
 *     NEVER white-on-orange (fails AA 2.93:1).
 *   - Display type: Inter Display Variable (Inter upgrade path if Migra licensed).
 *   - Body: Inter Variable. Handwritten: Caveat. Mono: Geist Mono / JetBrains Mono.
 *   - All tracking negative — Apple philosophy scales beyond hero.
