/* Cruise Photo-Booking Recommender — dark UI, no external font (Google
   Fonts would be blocked by this project's CSP style-src, and the shared
   duit-sampingan app already hits that same limit), no external JS lib.
   Sizing is tuned for one-handed touch use (this runs on a phone on deck,
   not a desk) — text and tap targets sized generously on purpose, not
   just for legibility but because 16px inputs also stop iOS Safari's
   auto-zoom-on-focus, which is its own usability bug otherwise. */
