// The peer range's lower bound is a compatibility claim; the exact devDependency pin is the only version this
// package is ever compiled and tested against. When they disagree the range claims support for versions nothing
// verifies, and nothing fails until a consumer resolves one of them.
//
// That is not hypothetical: the range shipped as ^7 while ConceptAs - used here as a runtime value, compared by
// class object in JsonSchemaGenerator - only exists from 7.14.0 onward, leaving 48 published versions that
// satisfied the range and could not link. Tying the bound to the pin is what stops the two drifting again.
