# Канонический production-манифест Chatballs (ADR-HUB-0028).
# Один Compose для: установки клиента, staging, smoke.
# Локальная разработка — через override compose.dev.yaml; этот файл не содержит
# dev source mounts, dev-команд и host-портов (кроме public 80/443 у gateway).
#
# Image references берутся из release.env (immutable digest refs, см. ADR §release).
# В dev они не задаются — срабатывают безопасные defaults, а override подменяет
# image на build.
#
# Запуск production/box:
#   docker compose --env-file .env --env-file release.env up -d
# Запуск разработки:
#   docker compose -f compose.yaml -f compose.dev.yaml --env-file .env.example --env-file .env up
