Detailed Description

A type-erased, non-owning runtime handle to a flag.

name and category are views into the flag type's static NTTP-backed storage, valid for the program lifetime (the same guarantee IconifySet::set relies on). display points at the flag's DisplayInfo when it is Displayable, else is null.

Identity is the flag name: two FlagRefs compare equal iff their names match.
