   pinnavaia.com — the design system (every page)
   The shell all pages share — apex, /daniel, and the hosted tools. Brand type
   (Fraunces + IBM Plex Mono + one gold accent) on solid, calm light/dark
   surfaces — no living sky, no motion. Left-aligned reading, not a centered
   splash. Paths are root-absolute (served at the site root), not file://.
