Craft.js uses several invariants as try/catched control-flow checks (notably isDraggable -> 'A top-level Node cannot be moved' for ROOT and linkedNode children). These fire on every render and are NOT errors — they're how Craft.js asks 'should I attach drag to this node?'. Filter them out of the shim's console.error so only genuinely-broken invariants show up.
