/* FoldFocus — site styles
 *
 * Drawn in the app's own material (FoldFocus/Views/Theme.swift): a dithered night sky, Silkscreen for
 * short uppercase headlines, Departure Mono for every number, stepped "pixel" corners, slab buttons
 * with a lip. Body copy stays in the rounded system face. Amber is window light: only the main action,
 * progress and the thing you're building are lit.
 *
 * Motion follows apple-design + emil-design-eng: feedback on press, transform/opacity only,
 * critically damped by default, bounce only where something lands, and gentler cross-fades under
 * prefers-reduced-motion. Mobile follows mobile-native: svh heroes, gated hover, no tap flash,
 * safe-area padding, 16px+ controls.
