/*
 * seatt.app
 *
 * The §9.2 tokens from `packages/app/src/design/tokens.ts`, transcribed. A
 * reservation card: cool paper stock, ink, a deep wine accent, times set in
 * monospace because times are data. Radius 4, not pills. No gradients and no
 * shadows — the app has none and the site should not look like a different
 * product.
 *
 * Typography is a system stack rather than a webfont. The app sets Space
 * Grotesk and IBM Plex; matching that here would mean either self-hosting
 * ~120KB of woff2 or calling Google Fonts, and the privacy policy is explicit
 * that visiting the site does not hand anyone to a third party. On the devices
 * that matter — anyone arriving from an App Store link — this resolves to SF,
 * which is a good face and already on the machine.
