# Traefik Dynamic Configuration for Blue-Green Deployment
# This file is watched by Traefik and reloaded on changes
# Traffic weights are updated by scripts/ci/switch-traffic.sh
#
# Current active stack is determined by weights:
#   - blue=100, green=0  -> Blue is active
#   - blue=0, green=100  -> Green is active
#   - Gradual: 75/25, 50/50, 25/75 for canary deployments
