Now that Usage and Settings are workspace pages instead of sheets (#23841), they still looked like sheets: #23841 forced an opaque header on them, and on the folded Duo on every root tab, Home and pull requests included. Usage's environment filter was a custom React view in headerRight, so the Duo couldn't move it into the vertical bar and it sat beside the title.

• Workspace roots, Settings and SettingsScreen pages keep the transparent glass header the stack already configures. Their scroll views already carry scroll-edge markers, so content blurs under the bar like threads and pull requests.
• Usage's filter is a native header menu item, the same shape as Settings' scope filter, so the Duo places it in the rail. Android keeps its existing menu.

Folded Duo simulator (the after captures happen to be in landscape):

	Before	After
Settings
Usage
Home	solid header (same override)

Also checked unfolded: Settings and Usage show the glass header with their filter at the trailing edge. check:changed passes. Like other unset Duo screens, Settings and Usage follow the system's minimize-on-scroll on the folded display; Home and the pull request lists stay pinned to never (#24295).

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This focused iOS UI change makes existing workspace pages use the glass header and moves the Usage environment filter into the native Duo rail. Because it changes the default presentation of existing product screens, the user-visible behavior merits human review.

Walkthrough

The mobile workspace screens remove explicit native stack header and content backgrounds. The workspace root now bases iOS header transparency on native liquid-glass support. The Usage screen supplies environment-filter actions through native header items.

Changes: Mobile native headers

Layer / File(s)	Summary
Workspace header styling apps/mobile/src/features/workspace/WorkspaceRootScreen.tsx	The workspace root now bases iOS header transparency on native liquid-glass support. It leaves content styling unset and removes the Usage-tab-specific headerRight override.
Settings header options apps/mobile/src/features/settings/SettingsRouteScreen.tsx, apps/mobile/src/features/settings/components/SettingsScreen.tsx	Both settings screens remove their iOS native stack options for header and content backgrounds.
Usage native menu apps/mobile/src/features/usage/UsageRouteScreen.tsx, apps/mobile/src/features/workspace/WorkspaceExtraTab.tsx	The Usage screen configures environment-filter actions through native header items. The extra tab no longer sets header items to undefined.
