+          You are implementing a specific change requested via Checkpoint. Read AGENTS.md first for codebase structure. Then read /tmp/checkpoint-context.json for the full element context (selectors, styles, DOM).

+          1. Read AGENTS.md for project structure
+          2. Read /tmp/checkpoint-context.json for element context
+          3. Use the CSS selector or React component name from context to grep for the source file
+          4. Make the minimal change to implement exactly what was requested
+          5. Do not refactor, do not add comments, do not touch unrelated code
