/* =============================================================================
   style.css — Design tokens, resets, typography, and base layout primitives
   for Venue24x7.

   DESIGN SYSTEM
   Color   — Wine (#6B1D3C) + antique gold (#B8894A) on warm ivory, evoking a
             mandap's fabric and metalwork rather than a generic SaaS palette.
   Type    — Fraunces (display, editorial serif with real weight) paired with
             Karla (body, warm humanist sans) and IBM Plex Mono for numerals —
             prices, dates and booking IDs read like ledger entries.
   Motif   — The mandap arch (the ceremonial four-pillar canopy) is the
             signature shape: it caps hero/card imagery and repeats as a
             toran-style divider between sections.
