/* base.css — Chow Ying travel tips (R1 blend design: Stripe typography ×
   Airbnb visuals, per samples-ui/sample-blend.html — Marc-approved).
   Stripe: Source Sans 3 weight 300, deep navy #061b31 headings, purple #533afd
   accent, blue-tinted shadows, 4-8px radii. Airbnb: rounded 24px hero carousel
   with circular prev/next + dots, photo-forward cards, share row
   (X/WhatsApp/Facebook/copy/like), IG CTA, footer 18-locale grid with Auto row.
   Keeps: R4 3-state theme toggle (Auto/Light/Dark), K9 mobile nav, K11 footer
   legal links. Mobile-first.
   Served from /travel/static/base.css (unhashed — nginx sets a 5m TTL;
   see K12 review: a 1y immutable cache would pin stale CSS in browsers
   because CF purge cannot clear browser cache). */
