The music wishlist has its artist 'nebula'; the TV side now has its own rich,
TV-native metaphor. Each show is a reel: poster + one horizontal film strip per
season (dark band with sprocket-hole borders) made of episode 'cells'. A cell
shows E#, glows in the show's hue, and widens on hover to reveal the title;
remove ×s sit on each cell, each season label, and the show header. Poster/title
open the show detail. Status tints the cells (wanted/downloading/done/failed).
Movies tab unchanged.
query_wishlist(show) now also returns library_id so reels open the owned detail
when applicable. Backend suites green.
