What to Try

• Markdown content: Notice how examples use headers, lists, code blocks, and emphasis -- MarkBack wraps Markdown naturally
• V2 headers: Use @id, @file, @tag, @input instead of V1's @uri, @source, @prior
• Valid examples: See properly formatted records with identifiers, structured feedback, and JSON metadata
• Error cases: Understand what breaks validation (missing feedback, invalid JSON)
• Edit freely: Modify any example and watch the diagnostics update in real-time
