 - **Home `/`**: a greeting, weekly listening stats, "continue listening" (recently played merged with the in-session history), the featured playlist with its first tracks (play and shuffle load the full list on demand), the user's mixes and playlists. Anonymous visitors are redirected to `/explore`.
 - **Explore `/explore`**: genre tiles when there is no query, otherwise search results grouped by songs, albums, users and playlists with filter chips and counts taken from the API totals. Songs paginate with infinite scroll. Track and album context menus offer play next, add to queue and add to playlist.
 - **Liked `/liked`**: the songs the user liked, newest first, with unlike per row.
-- **Library `/library`, `/library/albums`, `/library/uploads`**: the manage-music area, one route per section behind shared tabs. Songs lists the user's uploads, filtered on the server (`?q=` and `?status=`) with counters, and lets the owner publish, unpublish and bulk delete them (a track is created unpublished and is only visible to its owner until published; processing tracks refresh on their own); Albums lists the user's albums and edits them at `/library/albums/new` and `/library/albums/:id`; Uploads is the upload queue: the browser sends each file straight to storage through presigned URLs (`/api/uploads`, with progress), `/api/uploads/complete` creates the track unpublished and optionally adds it to an album, and `/api/uploads/status` follows the processing. Genres and cover apply to the whole queue and the queue survives tab changes. `/upload` redirects here.

Each song has a Coautores action that opens a dialog to invite users (searched through `/api/users/search`, picked as chips in a `TagInput`) and to see or remove the invitations with their status (pending, accepted, rejected). Invitations sent to the user land in the Invitaciones tab, which shows a count badge and lets them accept or reject each one; accepted coauthors are linked next to the artist wherever a track is shown (lists and the player).
 - **Albums `/albums`, `/albums/:id`**: list and create albums. The owner can edit, delete and add or remove tracks from their library.
 - **Playlists `/playlists`, `/playlists/:id`**: list and create playlists. The owner can edit, delete and remove tracks; everyone else gets a read only view.
 - **Mix `/mixes/:id`**: a generated mix with play, shuffle and a track menu.
