// 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, recorded application resolution, and structured load errors.
// Composition, profiles, semantic validation, overrides, secrets, and effective
// rendering are not available yet. The configuration contract is documented in
// docs/config.md.
