/*
  Omoikane — design system.
  Single source of truth for both the public Hugo site (www/, beta/) and the
  daemon/mockups/ post-login HTML scaffolds. Tokens declared once, primitives
  used everywhere. Self-host fonts later (Cormorant Garamond + Inter); for
  now the system fallbacks are good enough.

  CSP-friendly: no remote font/script imports. No third-party trackers.
  Per omoikane mission rules.
