Two creator directives, 2026-11-01.
**Ctrl-down dismisses an open zoom box.** Window-level PreviewKeyDown, so the same hand that
opened it can put it away. It cannot cancel itself at creation: Ctrl is already held before
the right-click that makes the box, so the keydown fires while nothing is open.
**Follow mode, default Anchor.** A PillToggle in App Settings ("Follow the box"), persisted
as Zoom.FollowBox. Off — the default — keeps the 2026-10-08 model: the capture stays on the
clicked point and dragging only moves the box over it. On, UpdateZoomMove re-anchors the
capture to the box centre (half the box's size, clamped per axis), so the magnifier shows
whatever it hovers. Flipping to Follow while the box is open snaps it immediately.
Three tests: anchor drags leave CaptureX alone, follow moves it to the expected quarter-offset
centre, and the setting round-trips through LayoutStore (tested against the store, not via two
view models — two live VMs fight over the temp DB, which is a fixture problem, not a bug).
Both new test classes share a collection tag: MainViewModel.LayoutPathOverride is static, and
xUnit runs classes in parallel, so without it the two view models collided (one failure in a
combined run, clean when run apart).
Release build 0 warnings; 14 tests pass across zoom, entitlement and preview history. Debug
build is blocked by the running app (PID 47388) — close it and the exe updates.
