Description

The Release component's scrobble interface has several usability gaps that make scrobbling cumbersome, especially for multi-medium releases. This task improves the experience across three areas: custom scrobble time, button visual clarity, and per-medium scrobble access.

Acceptance Criteria

• #1 The release-sheet header renders a Finished at date/time picker that displays 'Now' when unset and an explicit time when set
• #2 The release-sheet header renders a solid-primary Scrobble release button that scrobbles the whole release using the picker value or DateTime.utc_now() when unset
• #3 The release-sheet header renders a ⋯ overflow menu containing Print tracklist, plus Connect Last.fm when the session key is missing
• #4 The duplicate top-level Tracks master checkbox shown on single-medium releases is removed
• #5 Each medium header renders a soft-primary Scrobble disc button that is enabled regardless of cross-medium track selection
• #6 Each medium header renders a ⋯ overflow menu containing Print tracklist for that medium
• #7 A sticky bar appears at the bottom of the sheet body whenever MapSet.size(@selected_tracks) > 0, showing track count, medium count, aggregate duration, and a Scrobble selected button
• #8 The sticky bar is not rendered when no tracks are selected
• #9 Scrobble selected scrobbles only the ticked tracks using the picker value or DateTime.utc_now() when unset
• #10 Clicking a per-medium Scrobble disc submits that medium regardless of selection elsewhere, using the picker value or DateTime.utc_now()
• #11 The picker has a reset affordance that clears the value back to 'Now'
• #12 Disabled scrobble buttons are visibly distinct from enabled ones in both light and dark mode (verified in browser)
• #13 On viewports ≤ 380px the header reflows: title row above a second row containing the picker (flex-1) and the Scrobble release button; per-medium scrobble collapses to icon-only; sticky bar stays legible
• #14 ScrobbleLive.Show per-medium scrobble handler works with tracks selected (regression test)
• #15 All new user-facing strings wrapped in gettext; .pot/.po files regenerated via mix gettext.extract --merge
• #16 New LiveComponent tests cover: default picker state, picker value propagating to all three scrobble handlers, sticky-bar rendering, and medium-button enabled-with-selection
