+# TraefikService — weighted load balancer between stable and canary.
+# THIS IS THE ONLY FILE YOU NEED TO EDIT to shift traffic weights.
+#
+# Weight scenarios:
+#   Initial canary test    → stable: 90  canary: 10
+#   Extended testing       → stable: 50  canary: 50
+#   Full promote to canary → stable:  0  canary: 100
+#   Emergency rollback     → stable: 100 canary:  0
