   DubaiQuest — Shared Design System
   Premium Dubai aesthetic: deep navy night sky, warm desert sand, gold
   accents. CSS custom properties drive per-location dynamic theming — JS
   overrides --color-primary/--color-secondary/--color-accent on
   :root (or on a themed container) when a neighborhood is chosen so the
   whole UI re-skins without touching this stylesheet.
