+# Standalone build target for the first bounded Bluetooth slice.
+#
+# This profile extends the existing minimal Red Bear baseline but keeps Bluetooth wiring isolated to
+# this profile instead of leaking it into the shared device-service fragments used by all images.
+# The current slice is explicit-startup, USB-attached, BLE-first, and intentionally not wired to
+# USB-class autospawn yet.
