+final result: blocked
+
+Target: Karl's selected first search/preview concept, combined with Raycast-style
+compact interaction and the supplied searchi brand board. Source images were
+opened and inspected. The frontend implementation is in progress.
+
+Rendered comparison is unavailable: the in-app browser bootstrap fails because
+its browser-service module cannot be found. Prior native Windows capture attempts
+returned GetCursorPos access denied and monitor capture error 0x80070057.
+No matching-state implementation screenshot has been captured. No side-by-side
+visual comparison or visual pass is claimed.
+
+Typography, spacing, colors, asset fidelity, and content must all be evaluated
+against a captured native app after access is restored. Keyboard navigation,
+progressive results, focus/selection stability, themes, reduced motion, and forced
+colors also require actual interaction verification. Compilation and unit tests
+are separate evidence and do not close this gate.
