// Package policy implements the Rego-in-Markdown policy package loader,
// validator, and evaluator.
//
// Per ADR-002 a policy package is a Markdown document with YAML
// frontmatter (metadata), prose intent sections, fenced rego rule
// blocks, fenced rego test blocks, and fenced yaml fixture blocks.
// Loader extracts blocks, runs opa parse and opa test, and evaluates
// fixtures before marking a package valid.
//
// Implementation lands in FLEX-WP-0002 P2.3.
