- 05-file-structure-rules: 1165-line authoritative ruleset covering 11 media
categories (movies, tv, anime, stand-up, concerts, docs, home video, extras,
subs, artwork, NFO). Architecture A flat layout chosen at
/home/user/media/{movies,tv,anime,musicvideos,music,home}. Top 3 gotchas
surfaced: no-per-item-folder breaks extras/NFO; year must be in parens;
anime absolute numbering past 99 needs Shoko or split-by-TVDB-season.
- 06-per-library-themes: 319-line research memo. Verdict: partially feasible.
No native per-library theming; CustomCss is global, Jellyfin web sets no
body class for libraryId/collectionType. Recommended approach: JS Injector
plugin (n00bcodr fork, MIT, last release 2025-12-08) + ~30-line shim that
mirrors topParentId/collectionType from URL hash to body class, plus three
scoped CSS blocks (body.lib-movies, body.lib-anime, body.lib-music).
Reaches 'tinted, branded, recognisable' — not pixel-perfect. Pixel-perfect
fidelity needs subdomain split (3 instances) at ~100x maintenance.
