Other shipped assets

Original SVG arenas use no league/team logos. The Statsplice header and favicon use the user-approved D artwork, cropped from the supplied original without redrawing or recoloring. Team colors are illustrative and not certified historical pigments. Fonts use system stacks. Current gameplay displays no player photos. Archived JPEGs are retained locally and excluded from production. The historical credit record is retained: each photograph's author, source, license/status, modifications and checksum. The local collection has individual CC BY, CC BY-SA and public-domain entries; retaining this record does not mean its images ship.

Archived Wikipedia table inputs
