+# FILE: cluster/applications/monitoring/dashboards.yaml
+# DESCRIPTION: Custom Grafana dashboards as ConfigMaps.
+#              Picked up automatically by the Grafana sidecar via label:
+#                grafana_dashboard: "1"
+#              searchNamespace: ALL means these can live in any namespace.
+#
+# NOTE: Community dashboards (gnetId) live in values.yaml under
+#       grafana.dashboards. This file is for custom/homegrown dashboards only.
+#
+# USAGE: Add a new dashboard by creating a new ConfigMap entry below.
+#        The data key must end in .json — Grafana uses the filename as the
+#        dashboard title source. Keep one dashboard per ConfigMap for clarity.
+# ------------------------------------------------------------------------------
+
+# Example structure — replace with real dashboard JSON when ready:
+#
+# apiVersion: v1
+# kind: ConfigMap
+# metadata:
+#   name: dashboard-mk-labs-overview
+#   namespace: monitoring
+#   labels:
+#     grafana_dashboard: "1"
+# data:
+#   mk-labs-overview.json: |
+#     {
+#       "title": "mk-labs Overview",
+#       "panels": [],
+#       ...
+#     }
