The gesture-nav strip below the in-app browser's control bar was painted
black by inset padding, but painted-only areas don't consume touches in
Compose — stray taps fell straight THROUGH the overlay into the kiosk's
tab bar behind it (accidentally opening the AIUI chat tab). The strip is
now an explicit Box: solid black AND click-swallowing. Bottom inset
moved off the Column padding so the shield can own that region.
