 * Mirrors the app's "ortholife" theme (mobile/src/core/theme/tokens.ts):
 * a photographic backdrop under a warm dark scrim, translucent cards with
 * thin white borders, white type, and a white pill for the primary action.
 * Values below are the same rgba() tokens the app ships.
 *
 * Dark-only on purpose — the app has one warm dark theme and does not follow
 * the system, so the site should not either.
 *
 * No web fonts: loading them from a third-party CDN would leak visitor IPs to
