# Overlay: make the CI compose stack usable from a HOST browser.
# Same two mechanisms infra/docker-compose.local.yml already uses — pin Keycloak's issuer to the
# host-published address, and point each portal's runtime config.json at it. The BFF needs no
# change: it discovers metadata over keycloak:8080 and the discovered issuer is the pinned
# localhost:8180, which is what browser tokens carry.
