/* =====================================================================
   HOMEPAGE — NHÀ HÀNG PHÌ LŨ
   Sections:
     1. Hero (split editorial)
     2. Introduction (framed two-column)
     3. Venue selection (.venues + .venue-card — styles in venues.css)
     4. Booking CTA (framed centered)
   Phase 12 — the hall preview 4-card section was replaced by the
   two venue cards in venues.css; only the surrounding section shell
   (.venues padding + .section-head spacing) lives here.
