/* ============================================================================
 * HOLO ART ENGINE
 *
 * Every picture in the kit (the glass cube grid on a card, the violet tubes,
 * the mosaic, the cobalt slabs, the dark tiled room, the concrete steps) is
 * PAINTED IN CODE by one hand-written WebGL2 ray marcher. Nothing is a photo
 * or a video, so an AI agent can retarget a scene by editing its map().
 *
 * How it stays cheap:
 *   - One shared offscreen WebGL2 context for the whole page, created on the
 *     first request and never per component.
 *   - A picture is rendered ONCE per (scene, size, seed) and cached as a
 *     canvas. Cards, pills and tiles draw the cached canvas into their own 2D
 *     canvas; nothing ray-marches per frame.
