{#
  Archetype: service-resources-v1
  
  Description:
    Resource limits (CPU/memory) for production deployments (schema 1.2+).
  
  Approach:
    - Standalone mode: Uses deploy.resources (Compose spec v3+)
    - Swarm mode: Includes reservations for resource guarantees
    - CPU limits specified as decimal (0.5, 1.0, 2.0)
    - Memory limits with units (512M, 1G, 2G)
  
  Usage:
    Use for production services that need resource constraints.
    Prevents resource exhaustion and enables better capacity planning.
