/* tasks/067 + tasks/070 — the no-login public speedboat-booking surface.
   A full-page booking-engine site (Escape structure, HotelOS light+teal skin) built
   ONLY on os-ds tokens (no raw hex) + os-* component classes. Every class here is
   hos-pb-* scoped: the tasks/070 rebuild replaced the shared-class overloading that
   leaked the landing's layout into the wizard pages. Search-widget field sizing lives
   under .hos-pb-searchw; form fields (.hos-pb-field) are plain stacked labels that never grow. */

   tops out at --text-3xl (28px); a booking-engine hero is deliberately larger, so
   these fluid display steps are declared as local tokens (referenced via var, kept
   off the UI type scale on purpose — tasks/070). */
