- Define 5-color semantic palette (Okabe-Ito derived, color-blind safe)
- Use classDef for reusable styles instead of per-node statements
- Limit node text to 2 lines max, move specs to tables
- Consistent node shapes by role (rounded for network, stadium for external)
- Dashed arrows for control plane, solid for data plane
- Tinted subgraph fills matching dominant role color
