Document all properties and their valid ranges

### Problem

All network properties---their significance, valid ranges, and interactions---are not documented in a single location.

### Solution

Provide such documentation.

### Alternatives

_No response_

The issue does not name files or tests. Start by locating the network property definitions and existing documentation, then inventory each property's significance, valid range, and interactions. Done means this information is collected in one clear, complete location.
