Example: Rugged Control Box

This example is derived from Exercise 1 and stays at the family-selection / documentation level. Project-specific values are intentionally left as TBD. The point is the structure of a complete interface definition, not the numbers.

The enclosure is a small sealed control box with these external interfaces: 24 VDC input, Ethernet, CAN, four sensors, one motor output, and one debug/service port. For selection reasoning on each of these, see the matching decision paths.
