/* =====================================================================
   Checkout layer  —  mobile redesign + palette A/B toggle
   ---------------------------------------------------------------------
   Everything here is keyed off <html data-checkout-preview>, which
   checkout_preview.js now sets unconditionally on every checkout page
   (the redesign is the default UI). The rules are still mobile-only media
   queries, so the wider desktop production layout is untouched.

   Two independent axes:
     1. LAYOUT  — a thumb-first single-column mobile flow + an always
        visible sticky checkout dock. Applies in BOTH palettes, mobile
        only, under html[data-checkout-preview].
     2. PALETTE — html[data-scheme="current"] (default, = live brand) vs
        html[data-scheme="aquatic"] (deep-navy + coral comparison).
        Colour-only; remaps the --houston-* tokens.

   Scoped to .houston-booking (field trips / birthday / private events /
   group admission) and .makeover-layout (event checkout).
   ===================================================================== */

/* Load sentinel: checkout_preview.js reads this custom property and refuses
   to mutate the DOM (relocate the calendar / order panel into the mock,
   restyle the nav) until it resolves to 1 — i.e. until THIS stylesheet has
   actually applied. Without the guard, a slow/dropped CSS request would
   leave the page torn into the unstyled mock. Keep this rule first. */
