/* Svaara 2.1 design system, following the Quiet Gesture UI/UX guidelines.

 * Token status
 *   VERIFIED     --color-brand-primary #0e6b62 is Svaara's existing product teal (icon, manifest, v2.0 UI).
 *   PROVISIONAL  every other value below is a new design decision. Quiet Gesture's own brand hex values
 *                and typeface could not be recovered from the live site, so update these semantic tokens
 *                centrally once the brand sheet is confirmed.
 *
 * System fonts only: works offline and needs no third-party requests (strict CSP: style-src 'self').
