  configmap_files — ConfigMap with arbitrary file payloads.

  For each entry in `@values`, the value is the basename of a file
  under `marea.d/configs/`; its raw contents are placed under the
  ConfigMap's `data:` block as a literal-block scalar (`|-`), keyed by
  the entry's key. Mount the ConfigMap as a volume to get one file per
  key on disk inside the pod (config snippets, nginx.conf, prom.yaml,
  …).

  Wiring (marea.yaml):

      releases:
        api:
          helm:
            template: configmap_files.yaml
            values:
              nginx.conf: nginx.conf        # <data key>: <file basename>
              prometheus.yml: prom.yml

  Assigns used: @name, @values, @config_files.
