Files page: folders, video-only listing grouped by series, lazy mpv thumbnails
Standalone FilesPage (plugged into the shell later): watched folders (sidebar, chips with remove when narrow), a header saying where you are, series sections and a 16:9 grid for loose videos, thumbnails requested only for tiles that stay visible and cancelled when scrolled away, hidden-files count with examples, rescan, Recent with missing-file state, play errors in a banner, offline browsing with play disabled.
