        #      APs (kicking every WLAN client) and `private-key="<<REDACTED>>"` to the
        #      core (killing the WireGuard hub). Sections containing the mask are
        #      excluded from any push.
        #   2. The AP template is never pushed line-by-line to a live device: it
        #      transiently sets vlan-filtering=no, which severs the vlan99 management
        #      path mid-session. Full re-provisioning goes via file upload + /import.

        # enable_postprocessing stays OFF on purpose: render_secrets would not fix the
        # compliance side (the stored intended would keep the un-rendered Jinja
        # expression -> permanent false positive) and pushing PSKs has no use here.
