// Base is a registry of all Grafana core kinds. It is designed for use both inside
// of Grafana itself, and for import by external Go programs wanting to work with Grafana's
// kind system.
//
// The registry provides two modes for accessing core kinds:
//  * Per-kind methods, which return the kind-specific type, e.g. Dashboard() returns [dashboard.Dashboard].
//  * All(), which returns a slice of [kindsys.Core].
//
// 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() when performing operations generically across all kinds. For example,
// a generic HTTP middleware for validating request bodies expected to contain some
// kind-schematized type.
