/* =====================================================================
   Beverly Hills Lux Ride — Comfort Hub
   Editorial visual layer. Single shared stylesheet for /comfort/ + all sub-pages.

   Design directive: read like an editorial spread, not a SaaS landing page.
   - Big confident serif headlines (Cormorant Garamond)
   - Tiny uppercase em-dash labels, generous letter-spacing
   - Hairline rules, no decorative blobs/orbs/icons
   - Real semantic <img> tags with lazy loading + width/height (no CLS)
   - One accent used sparingly
   - Confident negative space; minimal card surfaces
   - Live primary CTA — shimmer + breathing shadow + arrow idle drift
   ===================================================================== */
