/* Metonic site palette + type.
   Palette: WARM DARK (dusk / brass / parchment) — committed 2026-06-17, see
   branding-visual-brief.md §8. Dark-mode-native, single brass "instrument"
   accent; the warm ground unifies with the parchment+ink app icon. Avoids
   calendar red / SaaS-blue gradients / neon. Type: system sans stack (SF on
   Apple) — license-free, zero dependency, on-brand for an Apple app. Colours
   live in :root below — the single edit point. */
