Both sides fixed the swallowed-click class on the onboarding picker.
Hers is the root cause: persistent 100% zoom through the app's own
setting, verified from both the renderer IPC and the BrowserWindow, and
re-applied before the dismiss loop — scale drift is what moved real
click points onto the wrapping container. The dispatchEvent fallback is
dropped: it bypassed hit-testing, so a leg could pass where a real
user's click would fail.
Comment-only conflicts in managed_uv.py and main_install_repair.py
resolved by keeping the fuller mechanism text (import-order reach and
the legacy hand-off scope).
