  ===========================================================================
  Fires when data-theme="the-quest". ARENA/GAMIFIED category (student-facing
  only per BUP-UI-THEME-001 Rule 2). Phase 2 target per catalog.

  SOURCING CLASS: [AUTHORED PROPOSAL -- pending owner approval; no source
  values existed]. BUP-UI-SKIN-002 SKIN-G04 (lines 67-72) describes this
  skin only in prose: "Rich greens, earth tones, and forest palette...
  dark with organic warmth. Lush. Adventurous." No hex values exist. This
  file authors a forest-green accent over a warm dark-brown/green canvas.

  Contrast check (WCAG AA, BUP-UI-SKIN-001 L-9): text-primary #f2ede0 on
  canvas #0e1409 = ~17.3:1. text-secondary #b9c79e on canvas = ~11.9:1 --
  passes 4.5:1 minimum.

   CONSTRUCTION FAMILY 5 of 8 — CRYSTAL GATE  [#234 / R-0823-01 / R-0823-02]
   Reference: six-terminals.html 02 "Crystal Gate -- faceted, emissive";
   ar-crystal-forms.html. Reuses the student crystal-gate chamfer construction.
   Frame strategy: a faceted slab -- two opposite corners cut (clip-path), a
   crisp outline and an inner offset hairline drawn as inset shadows on
   pseudo-elements that carry the same clip; two diagonal light shards inside.
   Light source: emissive from inside (inset glow + text glow). The outer halo
   is deliberately absent: clip-path would cut it (clip order: filter, then
   clip), so the light stays inside the crystal.
   Palette discipline: deep green/earth gradient, one emissive hue.
   Type: semibold, wide-tracked uppercase headings with a soft glow.
   NOTE: no backdrop-filter on any clipped element (the #228 paint-outside bug).
   [PILLAR-1: Gestalt -- the cut corners create a strong silhouette; the
   student crystal-gate is the validated precedent for this construction.]
