Patch Changes
- 337bcc5: Fix visual plan layout polish: compact question previews, mark wide-eligible tabs for diff-like content, align drag handles with wide blocks, and theme custom HTML iframes for dark mode.
- 337bcc5: Move the sidebar Connect AI setup card above the composer and stack its actions.
- 337bcc5: Keep the wireframe style toggle outside the Rough.js measurement scope so sketch mode no longer draws a ghost outline for the hidden Clean button.
