/* ============================================================
   SNS Valley View — Reserve modal

   A CSS-only dialog built on <details>, opened by the header's Reserve
   button. See web/templates/reserve.templ for why <details> and not
   <dialog>, and why the <summary> doubles as the backdrop.

   No new design vocabulary: --c-bg-card ground, --c-hair rules, the gold
   accent on the label and the × only, radius 0, no shadow, --dur/--ease
   on every transition.
   ============================================================ */
