A min-width clamp kept an incoming tab at 48dp until its label passed ~4dp while the outgoing label shrank immediately, so the tab row dipped left and then grew right. With the tab naturally 48dp wide (8dp/16dp padding around the 24dp icon) the width tracks the label continuously and the row moves one way.
Replace minimumInteractiveComponentSize (which centred the whole tab content and drifted as the active label expanded) with an explicit 48dp touch target whose content is aligned to the start. The icon position no longer depends on the label width.
Tracking the content position per frame made the inactive-tab colour split chase the layout instead of only following the indicator, so the icons jittered on a swipe. Go back to the stable tab-relative offset.
- offer a Sync button on a truly empty library tab so an empty library is not stranded (pull-to-refresh needs scrollable content)
- do not close the search field when it auto-syncs from a tab with an empty term
- make rememberArtworkColors nullable so the no-track fallbacks are live and the idle theme is the monochrome background
- measure the tab overlay content offset so the colour clip accounts for the touch-target centering
- put the pull indicator below the status-bar scrim, and seed the tab bar height estimate to avoid a first-frame inset jump
- collapse the two equal clearance constants, drop the redundant search imePadding, reuse the hoisted artwork for the mini player, and de-duplicate the mini player screenshots
- the indicator now uses the artwork primary and player surface instead of the default onSurfaceVariant
- keep the tab bar height in the list inset while searching so the content does not expand for a frame before the keyboard lands
- replace the library sync button with pull-to-refresh on every tab
- hide the tab bar while searching so only the search field sits above the keyboard
- animate the mini player progress bar between full bleed and 8dp inset rounded ends as the tab bar comes and goes
- make the warm-hue saturation damping continuous across the 0/360 hue wrap
- restore the library sync control removed when the tab bar was reworked, with a test that clicks it
- lift the search field above the tab bar instead of overlapping it
- give the tabs and settings/sync buttons 48dp touch targets
- drop the duplicated label semantics on tabs
- animate the library bottom inset so the bar does not jump when the mini player enters/exits
- remove imports and a parameter left dead by the header rework
