v1.3.0 — the sources, cited

The About page now carries a References section: one entry per pattern — 30 of them — with the primary source behind each, and a resolvable DOI wherever one exists. 19 works are credited by DOI, and each is recorded in this deposit's metadata as a cites relation, so the literature this project rests on is linked from the archived record rather than only named in prose.

Six entries are marked original construction. That marks the composition and the parameterisation as this project's own — never the mathematics, which is classical in every case and cited alongside.

Also in this release

• Per-page share cards. Home and the three galleries each have their own Open Graph card, in English and Spanish, served from real paths. Previously every page shared one image, and the Spanish card was never served at all — the document declared two og:image tags and crawlers take the first.
• Audio-reactive colour on the animate stage, off by default: spectral centroid to hue, level to chroma, in OKLCH, decaying back to monochrome in silence.
• A second hue axis. HUE SPREAD parts paper's hue from ink's, so a muted ground can sit under a differently-tinted mark. Default 0, which reproduces every existing palette byte for byte.
• Intrinsic motion for 17 patterns, which now move on their own during silence rather than only when audio drives them.
• Four demo tracks on the stage, and a curated video gallery.
• The pattern count is corrected to 30 throughout — it had been stale at 25 in the READMEs, the docs, the deposit metadata and the social cards.
