Frame0 wireframe driving T-275: a persistent permission-mode icon-button
trailing the composer text box, with per-mode resting variants (default /
accept-edits / plan), the open-dropdown state (active marked, bypass divided
off + guarded), and the D-78 interaction-zone state (prompt replaces the
composer; status-bar badge persists as the mirror). Embedded design notes
capture the prompt-mode interaction and the keep-the-status-badge decision.
