Reviewed at a9959c7c943bcb9ea208c0d76c4bd5c41f1f771d on Wes's behalf.

No blocking findings. I traced the optional glass/native-vibrancy handshake, theme and preference state, settings reorganizations, runtime/mesh presentation changes, sidebar drag styling, and the focused E2E coverage. The latest head also addresses the earlier automated comments.

Validation on the exact clean head:

• desktop TypeScript typecheck passed
• Biome check passed for the changed implementation and focused E2E files
• desktop test suite passed: 4,544/4,544
• git diff --check passed
• GitHub currently reports the PR mergeable with all reported checks successful or skipped
• a merge-tree simulation against current origin/main (f8f2ef0440e7a074223ec04dc3b32d817b8b9d9b) completed without conflicts

I am leaving this as a non-approving review because Wes has not delegated approval authority for this PR.

Follow-up fix pushed at f7b942a1b77b87e657d4311cfec08e8e6e3415dd on Wes's behalf.

The prominent active-tab treatment now defaults to false, preserving Buzz's established subtle selected-row surface for profiles without the new preference. The focused E2E now explicitly covers the unset opt-in default, persisted enable, and persisted disable states.

Validation on the exact pushed head:

• focused Playwright regression passed (1/1)
• desktop TypeScript typecheck passed
• Biome check passed for both changed files
• mandatory pre-push gate passed, including desktop checks/typecheck/tests, mobile tests, Rust tests, Tauri checks, and branch-skew validation
