syncInstances rebuilds an instance's subtree from the master, so a node dropped, pasted, duplicated or moved into an instance vanished from every page on the next master edit. Chosen approach: BLOCK (not preserve-on-sync): - every resolver component's Craft canMoveIn/canMoveOut refuses a canvas inside an instance (canvas DnD, Layers DnD, actions.move); synthetic shell-inner nodes now carry the component's rules instead of hardcoded allow-all - insertBlock (BlocksPanel / EmptyContainerAdd / palette), paste (menu + shortcut), duplicate (menu + shortcut) and Sitesmith patch/section replace redirect to after the instance or refuse; no empty-container '+' inside one The instance root still moves/duplicates as a whole; content overrides are unchanged.
