+# MeshCore Canada MC2MQTT broker preset.
+#
+# MeshCore Canada is the operator of the public MeshCore Packet Analyzer
+# infrastructure. These brokers speak the MeshCoreToMQTT (MC2MQTT)
+# protocol with the "letsmesh" format flavor, which today shares the
+# canonical MC2MQTT topic structure (meshcore/{IATA}/{PUBLIC_KEY}/...).
+#
+# Reference all MeshCore Canada endpoints with: brokers: [{preset: letsmesh}]
+#
+# Note: order matters for backward compatibility with the legacy
+# letsmesh.broker_index field. Index 0 is Europe, index 1 is US West.
+#
+# Optional UI metadata. Consumed by the GET /api/broker_presets endpoint
+# so the React/Vue admin can render this preset in the "From Template"
+# dropdown. `display_name` and `website` are advisory only — they are
+# never read by the runtime broker connection code.
