/* Commuter — "Midnight Flash" design system.
 *
 * The single source of truth for the app's identity. This file is blocking and
 * SW-precached, so it paints BEFORE the Tailwind Play CDN has evaluated. That
 * ordering matters: the CDN compiles asynchronously and only once
 * document.body exists, so there is always at least one frame with no Tailwind
 * CSS at all. Anything load-bearing (page background, base type, surfaces,
 * component shapes) lives here; tailwind-theme.js is an ergonomics layer that
 * exposes these same tokens as utility classes.
 *
 * Conventions:
 *   - No colour literal belongs outside this file.
 *   - Warm-tinted neutrals (hue ~40-60), never blue-grey, never pure #000/#fff.
 *   - Exactly one glowing element per screen. Destructive actions never glow.
 *   - Motion is expo-out. Never bounce or elastic.
