- Add `docs/` — Next.js 15 app powered by Fumadocs with a landing page, docs layout, search, OG image generation, and LLM text routes
- Cover getting started, configuration, integrations (Plex, Emby, Jellyfin, Radarr, Sonarr), mobile app setup, and telemetry in MDX
- Exclude `docs/` from root Biome config since it has its own `biome.json`
