/* Monio site — shared styles for the blog (and future marketing pages).
   Brand tokens mirror lens/src/index.css + the landing (warm paper, teal,
   indigo/rose duality). The landing page is self-contained; this file backs
   the /blog surface so posts share one source of truth.
   Fonts are self-hosted (same files the app ships, per DESIGN.md) — no
   third-party font CDN, so no extra sub-processor on the marketing site. */
