/* ============================================================
   PICE-EPSA 25th Anniversary — Enhanced Design System
   Inspired by ASCE ICTD's authoritative conference-site layout:
   full-bleed hero, segmented sections, card grids, dense footer.

   Brand colors are UNCHANGED from the original build:
     Navy #1B3A6B · Gold #A8B5C0 · White #FFFFFF
   Only usage, hierarchy, and spacing have been refined.

   Spacing rhythm: 8px base unit (--space-1 … --space-16)
   Typography scale: modular, Playfair Display (display) + Inter (body)
