Multi-scroll support: build.py and fetch.py take any open-data scroll (per-scroll voxel size, X-ray scan, renumbering by radius, optional ink, a second 1 um ink layer), make_manifest.py, the scroll picker's prize eligible badge and eligible-only toggle (window.unrollScrolls), and a 'Why N ink layers?' box written from each manifest's ink layers
Ink Bench: score your own ink prediction against the published ink, in the browser, with a Python and CLI companion, an open bundle format, a leaderboard view and Apache-2.0 code
- scrolls/index.json registry and per-scroll manifests (windings with ranges, ink layers with sources and resolutions, credits, data terms); PHerc. 139 migrated with no visible change
- scroll picker (hidden with one scroll), per-scroll and per-winding lazy loading
- lib/manifest.js validator shared by the page and tools/validate_scroll.mjs; docs/ADDING_A_SCROLL.md; tools/precompute_template.py
- Open your own: files, folders, zips or a URL, read in the browser only (nothing uploaded), OBJ/PLY with UVs, PNG/JPG/TIFF layers, size limits, clear errors, kept in IndexedDB and labelled local; downloadable synthetic example package
- atlases as WebP with JPG fallback (about 2.1 MB smaller)
- rename layers: Published ink (2.4 µm) and Our ink model (9 µm)
