# version is obsolete in newer docker-compose versions
#
# Environment-aware Docker Compose configuration
# Supports both production (fellowship) and local dev (fellowship-local) stacks
# Usage:
#   Production: cp .env.prod .env && docker-compose up -d         (containers: fellowship_*)
#   Local dev:  cp .env.local .env && docker-compose up -d        (containers: fellowship-local_*)
#
# The COMPOSE_PROJECT_NAME environment variable controls container naming:
#   - Omitted or 'fellowship' → containers: fellowship_backend_1, fellowship_frontend_1
#   - 'fellowship-local' → containers: fellowship-local_backend_1, fellowship-local_frontend_1
#
# This allows both environments to coexist without conflicts.
