The root tab header (avatar + title) no longer turns into a floating pill. It now scrolls away with the list. Feed's For You / Latest and Trending's category pills sit in one glass pill bar. That bar scrolls up with the list and then pins under the status bar. While pinned, it slides away on scroll down and returns on scroll up, together with the tab bar.

• MobileRootHeader: plain row that moves with the scroll offset. The header fade and the capsule are gone; the status bar fade stays.
• FloatingSubHeader: wraps its children in a content-width GlassCapsule, pins at insets.top + 8 so the status bar fade ends where the glass starts, and hides by sliding off instead of fading.
• GlassChromeContext: useHeaderFloatProgress is replaced by useHeaderScrollOffset / useSubHeaderScrollOffset. The chrome now stays shown until the title row has scrolled away (it used to be a fixed 40px).
• FeedTabs / TrendingHeader: the pills drop their own horizontal scroll view and padding.
• Notifications has no pills, so its header scrolls away and nothing stays pinned. Library and Explore are unchanged.

Tested on an iOS 26.5 sim (Release build, dark mode): Feed, Trending, Notifications at rest, mid-scroll, pinned, hidden on scroll down and back on scroll up. Not checked on Android or in light mode.
