  configmap_env — ConfigMap with env-style keys.

  Reads a YAML file from `marea.d/configs/`, treats each top-level key
  as an environment variable, and emits them under the ConfigMap's
  `data:` block with UPPER_CASED keys and stringified values. Mount it
  with `envFrom:` on your Deployment to inject the whole bundle as env
  vars in one go.

  Wiring (marea.yaml):

      releases:
        api:
          helm:
            template: configmap_env.yaml
            values:
              file: api.env.yaml   # basename under marea.d/configs/

  Assigns used: @name, @values["file"], @config_files.
