capacity property
Capacity is a human summary of what the machine has ("8 vCPU / 32G", "1× GB10"), up to 256 characters. Prose for a card — Spec is the same thing in a form a scheduler can read, and nothing derives one from the other.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
String? capacity;
