Massive tiled meshes of St Peter's Basilica streamed in the browser — renderer arena (three / Cesium / Babylon / R3F), COLMAP camera-pose reconstructions, benchmarks and docs.
Camera state lives in the URL hash (ENU metres around the basilica, Z-up) and is shared by
every viewer — use the top-bar links inside any viewer to jump renderers at the same spot,
or "copy link". Requires the read-only NAS tile server: npm run tiles
(serves \\freya\...\03_Deliverable\Mesh at localhost:8801, GET-only).
