 * MintChip — website design system.
 *
 * Values are taken from the app's own tokens (src/theme/tokens.ts) rather than
 * re-picked by eye, so the site and the app cannot drift apart:
 *   - background        homePalette.background* (the mint-sky-aqua recipe)
 *   - card + shadow     homeRadius.card / homeShadowV2.card
 *   - text              homePaletteV2.textPrimary / textSecondary
 *   - accents           homePalette.accent*
 * Type scale is NOT copied from homeFontSizeV2 — those are device-point values
 * for a 402pt phone frame and read microscopic on a desktop viewport. The
 * relative hierarchy is preserved, the absolute sizes are re-based for web.
