- Add `preview="edit"` to the WMD editor in the create dialog,
create popover, and edit dialog so users land in a ready-to-type
state rather than an empty preview pane.
- Add a CDP-based verification script (.cdp/verify-fix.cjs) that
drives a headless browser through the repro flow to confirm the
fix and capture console exceptions.
- Include a screenshot (shots/repro-preview-empty.png) documenting
the prior empty-preview bug for reference.
