/* ══════════════════════════════════════════════════════════════════════════
   TRIPTYCH PRESET SELECTION PANEL — design language
   ──────────────────────────────────────────────────────────────────────────
   Matches the Action Shot left-column pattern: image card + name label below.
   Each card reads as a UI choice, not a browsable gallery thumbnail.
   Rules:
     • 2-column grid — large enough to read the image at a glance
     • Flex-column card: image (square) + text label footer below
     • Label text pulled from data-gallery-display via CSS attr()
     • ::after = persistent label footer on every card
     • ::before = ✓ badge inside top-right corner when selected
     • Gold border + gold label on selected state
     • No hover scale — border brightens instead (scale = zoom, border = choose)
     • Size slider hidden — layout is fixed
   !important on layout props overrides workflow_unified.css flex + JS var. */
