feat(theater): full-screen detail body, eased content collapse, playing-release scoping

Browse Source 
Detail bodies fill 100vh below the nav so the visualizer reads full-screen; Theater toggle eases page content and the player-bar now-showing panel in/out instead of popping (reduced-motion honored); Theater only applies to the currently-playing release.
