 The action reads the `.codeboarding/analysis.json` that was committed at the PR base commit. If your repo has never been analyzed, the first PR will skip the diff and post a "no baseline yet" comment.
 
-To create the baseline, run the existing CodeBoarding docs workflow once on `main`. It will commit a fresh `analysis.json` to `.codeboarding/`. After that, every PR shows what changed.

 - **No focus / crop mode** for huge diagrams with tiny changes — the whole graph is rendered. Coming in V2.
 - **Re-clones the target repo** inside the analysis engine (legacy `generate_analysis()` API). One extra clone per run; harmless but measurable on huge repos.
 - **Image branch grows unbounded.** A scheduled cleanup workflow is on the roadmap.
+- **Webview bundle is committed in this repo** (`webview-dist/`). Until the upstream `CodeBoarding-vscode` repo ships its dist as a public release asset, rebuilding is a manual step: `cd CodeBoarding-vscode/webview-ui && npm ci && npm run build`, then copy `dist/` into this repo's `webview-dist/`.
