// Base is a registry of kindsys.Interface. It provides two modes for accessing
// kinds: individually via literal named methods, or as a slice returned from
// an All*() method.
//
// Prefer the individual named methods for use cases where the particular kind(s) that
// are needed are known to the caller. For example, a dashboard linter can know that it
// specifically wants the dashboard kind.
//
// Prefer All*() methods when performing operations generically across all kinds.
// For example, a validation HTTP middleware for any kind-schematized object type.
