   LATENTPHOTO — V7
   Horizontal-scroll carousel pattern · extensible
   ============================================================

   ARCHITECTURE NOTES
   ------------------
   This layout uses the industry-standard "scroll-carousel" pattern
   for visual selection (App Store, Netflix, Spotify, etc.).

   To ADD a new option in any existing category:
       Just append one <div class="card" data-value="..."> inside
       the matching .card-scroller. CSS does the rest.

   To ADD a new category (e.g. "Texture", "Color Grade"):
       1. Add a new <section class="panel panel-scrollable panel-X">
          with the same internal markup pattern.
       2. Update .studio grid-template-rows.
       3. CSS for card art is the only category-specific code.

   To CHANGE panel height: edit .card width/min-height only.
       Panels auto-fit because they hold one scrollable row.

   To SWAP scroll for wrap on a specific panel: remove the
       .panel-scrollable class on that <section>. Card layout
       falls back to a horizontal flex row that wraps if needed.
