# configuration for a static bundle. It has to be an environment variable here

# because .dockerignore excludes .env*, so no env file ever reaches this stage —
|
|
# and without a value the client falls back to a relative /api/v1, which the

# nginx runtime stage below serves as a static path. That answers a login POST
