Add per-session zoom state, route the zoom factor through the desktop preview bridge, and apply it to the Electron WebContentsView before preview capture so screenshot and annotation coordinates stay on the native preview surface.
Tested:
- cd desktop && bun run test -- src/components/browser/BrowserSurface.test.tsx src/stores/browserPanelStore.test.ts src/components/workbench/WorkbenchPanel.webview.test.tsx src/lib/previewBridge.test.ts src/lib/desktopHost/electronHost.test.ts
- cd desktop && bun test electron/services/preview.test.ts
- cd desktop && bun run lint
- cd desktop && bun run build
- cd desktop && bun run check:electron
Not-tested:
- cd desktop && bun run check:desktop (blocked by existing MessageList relative-time assertion and TabBar AbortSignal errors)
Confidence: medium
Scope-risk: moderate
Previewable changed-file rows no longer show a redundant workspace chevron when the row already has an Open With control. The unified Workbench now owns the Browser entry point, and opening Browser mode creates a blank address bar instead of navigating to a hard-coded localhost port.
Constraint: Keep explicit preview links and localhost output cards able to open the browser directly with their target URL.
Rejected: Keep the top toolbar browser button | it duplicated the Workbench Browser tab and silently opened localhost:5173.
Rejected: Use localhost:5173 as the blank browser default | it makes arbitrary Browser mode look tied to a dev server.
Confidence: high

Routes preview://event (navigated/ready) from Rust into the browser store via a new subscribePreviewEvents subscriber; adds title field and setNavigated/setReady reducers to BrowserSessionState; BrowserSurface subscribes on mount to replace M1 optimistic nav-state.

Per-session in-app mini-browser state: current URL, back/forward
history stack (historyIndex with forward-truncation on navigate),
loading flag, and element-picker toggle.
