+# Detects system environment: OS type, Docker, Compose, Frigate, go2rtc.
+# Fast, silent, returns JSON events to stdout.
+#
+# Protocol:
+#   - Every action is reported as a single-line JSON to stdout.
+#   - Types: check, ok, miss, error, done
+#   - Exit code: 0 always (detection never "fails", it just reports what it finds)
+#
+# Usage:
+#   bash scripts/detect.sh
