CI run 33814429514.

Review GitHub's image diffs, then merge this PR (or enable auto-merge) to apply the
accepted references to claude/interpreter-eval-ux-dv8apk. This branch contains
only PNG candidates from the immutable
reference-screenshot-candidates-33814429514 artifact and never targets main.

If the parent branch has advanced beyond the source SHA above, do not merge this PR;
the successful CI run for the new head will replace it.

  _{Static demo of the renderer against a mock API — the browser pane, terminal, and all main-process IPC are stubbed, so it never proves main-process behaviour. Rebuilt whenever a push changes the demo bundle; these links go live once the queued deploy lands, shortly after this comment. Removed when the PR closes.}
