"""Hub native-confirm gate (take-two F-16, the hub sibling of drill F-11) — native confirm()/
prompt() dialogs are OS-modals that freeze browser automation (CDP) and are banned from the hub
UI; consequential buttons use the inline felhomConfirm helper (templates/inline_confirm.html).
The danger-zone typed-confirm flow does not use native dialogs either.

Run from the repo root:  python scripts/hub_confirm_gate.py
Exit 1 if any native confirm(/prompt( call remains in hub templates.
