/* Archetypes — archetypesapp.com
 *
 * Token values are MIRRORED from the app's design system, not invented here. The single
 * source of truth is ios/Sources/ArchetypesDesignSystem/Tokens/ArchetypesColors.swift
 * (`defaultLight` / `defaultDark`), which Android mirrors via the same slot names. Slot
 * names below are kept verbatim so a drift is greppable across all three surfaces.
 *
 * Light is the DEFAULT brightness (matching the app since the 2026-06-30 theming overhaul);
 * dark is served via prefers-color-scheme from the `defaultDark` set.
 *
 * Fonts are SELF-HOSTED (subset to woff2 from the same .ttf the app bundles in
 * ios/App/Resources/Fonts/). No font CDN — deliberately: a third-party font host would be a
 * data flow this site's own privacy policy would have to disclose.
