// Package configkit provides deterministic, application-owned configuration
// loading for Go programs.
//
// Load currently supports one file, byte, reader, or explicit no-input source with
// strict YAML, typed defaults, schema-version checks, detached metadata, safe
// diagnostics, and structured load errors. Composition, profiles, application
// resolution and validation, overrides, secrets, and effective rendering are not
// available yet. The configuration contract is documented in docs/config.md.
