/* ============================================================
   PHAROS LUMEN - retrofit design system (2026 rebuild)
   "Daylight" token set (Gabriel's pick, 2026-07-17): light
   blue-tinted canvas, azure primary + sky secondary, white
   surfaces, deep harbor navy reserved for rhythm sections
   (method, explorer, footer) and the calculator result card.
   No dark page grounds (Gabriel: avoid dark; loves blue+white).
   Motion tokens mirror the Terminal teardown
   (back-office/docs/terminal-retrofit/terminal-teardown.md).
   Loaded by the rebuilt index.html only; about/privacy still
   run on pharos.css until their restyle (M4).
