/* ============================================================
   Fantasea Charter — design tokens
   Palette: deep night-sea navy, warm brass fittings, sea-glass
   teal, foam white. Display type is an old-world serif (Fraunces)
   used sparingly; body is a clean humanist sans (Public Sans);
   ship's-log details use a monospace (Space Mono).
   Signature element: the porthole — a circular, brass-ringed
   frame used for crew photos and gallery images throughout.
