/* ============================================================================
 * app.js — SZL COSMOS · Hanan Pacha  (sovereign 3D, vendored Three.js + bloom)
 *
 * CONSOLIDATION: folds three former Spaces into ONE holographic destination —
 *   - org-map            -> the ORG CONSTELLATION layer (live HF Spaces as nodes)
 *   - cathedral          -> the brain-sun + internal capabilities + field node
 *   - khipu-constellation-> the receipt-star constellation + cord arcs (DAG)
 *
 * UPGRADE over cathedral:
 *   - REAL postprocessing bloom (EffectComposer + UnrealBloomPass + OutputPass),
 *     all MIT, VENDORED under ./vendor — still 0 CDN at runtime.
 *   - Holographic shader material: fresnel edge + iridescent hue shift +
 *     scanlines + subtle projection flicker (light, not matter).
 *   - A polar hologram floor grid for depth.
 *
 * HONESTY DOCTRINE v11 (machine-checked against live endpoints):
 *   Λ = Conjecture 1 (advisory, NOT a theorem).  Khipu BFT = Conjecture 2.
 *   locked-proven kernel = EXACTLY 8.  Trust = conformal (never 100%, NOT Hoeffding).
 *   Org constellation = CATALOG snapshot (honest, not runtime-live); live health is
 *   polled only for CORS-open endpoints (a11oy, killinchu). Nothing fabricated.
 *
 * Sovereign: Three.js r160 (MIT) + OrbitControls + postprocessing vendored. NO CDN.
