/* ═══════════════════════════════════════════════════════════════════
   Roomframe AI — site design system (2026-08-27)
   Direction: dark editorial luxury. Fraunces (display serif, self-hosted
   — remote Google Fonts is a GDPR finding in DE courts) + Instrument Sans.
   Warm near-black, gold hairlines, film grain, one signature interaction:
   the draggable before/after comparator.
   Legal pages (privacy/terms) intentionally stay on the old style.css —
   reviewed by Apple as-is, they don't get redesigned as a side effect.
