/* Cure Crystals — curecrystal.com
 *
 * Design system and motion rules: docs/design.md.
 *
 * Constraints this file lives under (see node_server.js CSP):
 *   - style-src 'self'  → no inline styles anywhere; everything is here.
 *   - font-src 'self'   → system font stacks only, zero font downloads.
 * Motion rules:
 *   - Animate only transform, opacity and background-position (compositor-only).
 *   - Never fade the LCP element (hero logo/h1/tagline, crystal photo) from
 *     opacity 0; they may move, but they paint on the first frame.
 *   - Content is visible without JS. js/site.js only hides (then reveals)
 *     blocks that start below the fold, so crawlers and no-JS readers see
 *     everything.
 *   - prefers-reduced-motion turns every animation and transition off.
