<!-- Decision, 2026-10-29 (D9): Auto Backup rules for Android 11 and lower
     (android:fullBackupContent). Exclude-only, no <include>: everything is
     still backed up EXCEPT the settings DataStore, which holds this device's
     identity (renderer UDN, kiosk return package, observed Cast device,
     last-known hosts). Restoring it onto a new device made that device
     impersonate the old one. Keep in step with data_extraction_rules.xml. -->
