/* Shared checkout shell -- structure/layout only. Every color, font and piece
   of copy is a CSS custom property or inline content set by the page itself
   (model-heresy.html, together.html, ...), so this file never needs editing
   to add another course. Structure mirrors /joyful-marketing-checkout/index.html
   (the one other working checkout in this repo) deliberately -- same grid,
   same skeleton/error states, same Stripe mount point -- so this is a real
   shared system, not a look-alike rebuild.

   Required custom properties (set per-page):
     --ink, --ink-soft, --ink-faint, --rule, --bg, --accent, --accent-soft
     --font-body, --font-display
   Optional: --card-bg (defaults to #fff), --card-border (defaults to a
   translucent --ink line). */
