- Split pan clamping: clampPreviewPan (drag/wheel-pan) stays narrow (Math.max(0,...) — content pins to center when smaller than viewport). New clampPreviewPanForZoom (Math.abs) gives the wide range only to cursor-anchored zoom, preventing middle-mouse drag from pushing content off-screen at low zoom levels. - Pin transform-origin invariant: comment on the stage div noting that resolvePreviewWheelZoom cursor math depends on center-center pivot. New test verifies a non-center cursor keeps the same content-space point fixed across a zoom step. - Remove dead Math.abs(oldScale) > 1e-6 guard — oldScale >= 0.25 always (clampPreviewZoomPercent floors at MIN_PREVIEW_ZOOM_PERCENT = 25). - Skip setSettledZoom re-render when the value didn't change — uses a functional updater that returns the previous state object when all three fields match, avoiding a React re-render cascade through Player.
