+# Glance pulls work-runtime:2.7.1 → room-runtime:2.2.5 as transitive deps.
+# Room 2.2.5 finds WorkDatabase_Impl via Class.forName() reflection, but its
+# consumer ProGuard rules don't keep _Impl classes, so R8 full mode (AGP 9+) strips it.
+# Remove when Glance upgrades to Room 2.7+ (which uses RoomDatabaseConstructor instead of reflection).
