+- [ ] Check [`quarto-dev/quarto`](https://github.com/quarto-dev/quarto) (the visual-editor / VS Code tooling repo) for roundtrip **snapshot** test breakage on the next **prerelease**. Pandoc Markdown-*writer* changes — e.g. display-math newline handling, bullet/definition-list indentation — change visual-editor roundtrip output and break `apps/vscode/src/test/examples/generated_snapshots/*.qmd`. If output changed, open a companion PR there to regenerate the affected snapshots. Before regenerating, confirm each change is *intended* Pandoc behavior and not a transient regression (a bad snapshot can freeze a bug — see [quarto-dev/quarto#944](https://github.com/quarto-dev/quarto/pull/944)).
