Detailed Description

one base-dimension term of a signature: which base dimension (by name-hash), and its rational exponent

The base dimension is identified by an FNV-1a hash of its name string, so an arbitrary — including user-defined — base dimension round-trips in a fixed 8 bytes with no central registry.
