"""
The Node page offers `connection_processes`, bounded by the machine's cores.

The node refuses a number above its core count, so a field that let one be
typed would be a field whose Save fails. The ceiling comes with the settings
(`cpu_count`, which the node adds and ignores when it is sent back).
