"""Video library organisation — the Radarr/Sonarr-standard naming seam.

A finished download must land at a canonical, server-identifiable path:
    <root>/The Matrix (1999)/The Matrix (1999) Bluray-1080p.mkv
    <root>/Breaking Bad/Season 01/Breaking Bad - S01E01 - Pilot WEBDL-1080p.mkv
Pure string logic — pinned here so a refactor can't quietly change the layout.
