   NFHOTEL HOTEL — DESIGN SYSTEM
   --------------------------------------------------------------------------
   One source for everything visual. The classes below are the contract from UI-Spec.md
   section 3: markup may only use names that exist here.

   No external fonts, no CDNs, no icon packs — the site must work
   offline. Bootstrap is deliberately not loaded: its .row collides with
   the spec's .row, and everything visual must come from the tokens below.

   Order: tokens → reset → layout → typography → surfaces → buttons →
   form → data → status → feedback → public → admin → responsive.
