# Runtime API URL Configuration
# The API_URL environment variable can be set at container runtime to configure
# where the frontend should connect to the API. This allows the same Docker image
# to work in different deployment scenarios without rebuilding.
#
# If not set, the system will auto-detect based on incoming requests.
# Set API_URL when using reverse proxies or custom domains.
#
# Example: docker run -e API_URL=https://your-domain.com/api ...
