/* Booking-page-only visual system (modules/booking/views/book.ejs).
   Deliberately NOT Tailwind utility classes, unlike every other view in
   this app — adapted from UI-UX-Audits/booking-page-platform-branded.html,
   a from-scratch design system built to fix the problems documented in
   UI-UX-Audits/booking-page-Audit.md. See book.ejs's own top comment for
   the full list of adaptations made from that prototype to the real app
   (real branding data, real attendee-collection form, dark mode, no
   simulated-phone chrome, etc).

   Dark-mode variants of these custom properties live right here under
   html.dark, rather than in the shared public/theme.css — that file's job
   is overriding shared Tailwind class names used across many pages; these
   properties are used nowhere else, so keeping both palettes together in
   one file keeps each file cohesive. */
