• Toolbar — Reposition + / ⋮⋮ live while hovered block resizes; disable pointer-events on every actions descendant for left-edge blocks; keep slash search in inserted block after plus button
• Popover — Distinguish synthesized hover from real hover; hide context label while searching; keep block settings menu visible and attached to dots trigger
• Block Manager — Skip cross-container auto-heal inside move group
• Tooltip — Anchor wrapper with position: fixed to survive page scroll; render above popover and survive UA stylesheet
