Right-click now creates a transient ZoomSceneElement at z-index 1 whose pixels are a genuine 2x magnified sample of the backdrop (live capture under art), composited into stream/recording like any layer while the output crop stays the tier. All shapes are centered on the click and clamped to frame; healed on load/scene-create, never persisted, hidden from the layers list + element template (IsZoomLayer). BuildCompositorOptions is now internal = always tier crop (test seam). ZoomFrameBuilder is a pure static sampler (box/2 window centered on the box center, single-slot cache) proven by a banded-backdrop test; LayerReorderPersistenceTests drag resolves rows by item since the collapsed zoom row shifts container indices. Also books TASK 51 (webcam background Remove + Blur) and syncs memory docs (HANDOFF, MyMistakes, indexes). Full suite: 405 passed, 0 warnings.
