 - **Board rename** (settled: this function stays in-app, unlike the pathfinder which dropped it with the inspector). Rename edits the board's frontmatter `title` only — the folder is never renamed by the app; the Finder document name is Finder's to change (01-storage-format.md's board-naming rule). A foreign rename landing while the popover is open resyncs the field from the snapshot only while the field is unfocused — a focused field keeps the user's keystrokes, the dirty-buffer courtesy applied here (settled).
 - **Board styling** — the embedded style editor (Styling ▸ Controls above).

A **Board Settings…** row opens the sheet — the popover's one setup affordance. **The Pro mode-none posture is header plus that door** (blessed 2026-08-06): with no repository the section stays — "Git" and the Board Settings… row alone — rather than vanishing, so the board's git story keeps its named place in the popover and the door stands exactly where a user looking for git will look.
