Detailed Description
The decoration a Registry applies to every metric created through it: a name prefix, default constant labels, and default display metadata.
Supplied to Registry::create(adapter, config) and live-reconfigurable afterward through the registry's setters, exactly like a Scope. A registry created without one starts with an empty decoration (its metrics report scoped == false until a setter installs a prefix or labels).
