Nooks unified Arnis block proof — presentation and renderer provenance

Presentation grammar: adapted from the local nooks-eleven-region-demo UI only. Its regional terrain, Overture structures, proxies, fallback planes, world pyramid, and hand-off code are not imported.

Brand: current canonical Nooks wordmark and Martian web fonts from site-public/brand/source-assets. Martian fonts use SIL Open Font License 1.1; canonical licence texts live under site-public/brand/source-assets/fonts/licenses.

Renderer adapter: state parsing, reusable state geometry, procedural atlas generation, and NVXM/NVXI decoding from prototypes/arnis-full-resolution-viewer under GNU AGPL-3.0. Its complete LICENSE and THIRD_PARTY_NOTICES.md are the canonical local notices.

World source: the one canonical Arnis geo-terrain field declared by the active manifest and registration, including its OpenStreetMap and terrain-input provenance. Reuse implies no sponsorship, partnership, endorsement, or token affiliation.
