{#
  Archetype: volumes-v1
  
  Description:
    Consolidated top-level volumes section supporting multiple modes:
    - Simple: Basic local volumes for standalone deployments
    - External: Reference pre-existing volumes
    - NFS: Network filesystem for shared storage in swarm
    - Swarm: Flexible mode supporting mount/local/NFS strategies
  
  Approach:
    - External volumes: No definition needed (external: true not used at top-level)
    - Standalone mode: Always uses local volumes
    - Swarm mode with mount: No volume definition (uses bind mounts)
    - Swarm mode with local: Simple local volumes
    - Swarm mode with NFS: Network filesystem with driver options
  
  Usage:
    Use as the single volumes archetype for all deployment types.
    Adapts based on volume_external, swarm_enabled, and swarm_volume_mode variables.
