An orbiting point cloud of all 8,424 indexed passages, with the 262 highlighted
ones lit and threaded in the order they were marked. Data comes from library-rag
(chunks + embeddings) projected to 3D with UMAP; the page never touches Postgres.
Projection is `airy` (n_neighbors=50, min_dist=0.8) and the palette is `frost` --
both chosen by eye against the alternatives. Note that airy shows the underlying
book-territory structure LESS than the tight projection the pre-flight measured,
so the 0.805 k-NN purity figure describes that one, not this.
Page weight: the wrapper adds 321 B gzip to the homepage's blocking load. `three`
(127 KB gz) and the payload (56 KB gz) are a dynamic chunk fetched after render.
It fails closed -- no WebGL, no payload, or a dead fetch leaves a plain page.
The payload is a static snapshot; the 5-minute auto-build rebuilds the site, not
the data. New reading reaches this map only when export.py is re-run.
