Bug fix release.
Fixed: a serious bug where, on setups with a screen stacked directly beneath another (e.g. a laptop's built-in display positioned below an external monitor, sharing the same horizontal range), the entire lower screen could get misread as "past the upper screen's bottom edge" — causing the pointer to be yanked back on nearly every move/drag there. If you have a 3-display (or any stacked) setup, this fix matters.
No other changes since v1.0.0.
Install
Same as before — download the .dmg, drag to Applications, right-click → Open the first time, grant Accessibility permission.
Upgrading from v1.0.0
Rebuilding/redownloading changes the app's code signature, so macOS will drop the previous Accessibility grant. After installing v1.0.1, re-enable DockAnchor in System Settings → Privacy & Security → Accessibility.
