Replaces the pinned glass pill bar from #14748 on the root tabs.

What changes

• At rest: the root header is the pre-glass original again: avatar, gradient title, white background, controls on the right.
• Scrolling: the header (and the controls row under it) moves with the list like normal content. Overscroll keeps the area above it filled.
• Collapsed: once the title row leaves, a small glass pill with the screen name slides in under the status bar. The screen's controls sit below it in a small glass bar, and they slide in as the in-flow row leaves.

Tab	Compact controls
Feed	For You / Latest, filter on Latest
Trending	Tracks / Underground / Winners, filter on Tracks
Explore	none; pill shows a search icon. The header stays put while showing search results.
Library	Tracks / Albums / Playlists pills (switch tabs)
Notifications	none

Notes

• Library: the category pills and the top tab bar now float over the tab lists through a custom tabBar. Each tab's banner and filter moved into the list header, and each tab keeps its own scroll offset (useLibraryTabChrome). Filtering with no results stays inside the list, so the input keeps focus.
• Glass tint: GlassCapsule takes an optional tintColor. The compact pills use about 70% of the page color, because the clear material was hard to read over track titles.
• Explore: the tab bar's search button scrolls back to the top before focusing the field.

Testing

• Swapped a Release JS bundle into a Release build on an iOS 26.5 sim (signed in) and scrolled each of the five tabs: at rest, mid-collapse and collapsed. Also checked overscroll, tab switching from the compact Library pills, and dark mode on Notifications.
• Not run on Android.
