// Strip the harness portion from an HCL example file.
// Landing-page snippets in examples/ contain a display snippet
// followed by a "# ===== harness =====" marker and config
// scaffolding that makes the file pass `clawpatrol validate`.
// Landing page sections render only what’s above the marker.

export function snippet(source: string): string {
  const i = source.indexOf("# ===== harness =====");
  return (i === -1 ? source : source.slice(0, i)).trim();
