/doc

Use Iroh (the documentation specialist agent) for this task.

1. **Read** the target documentation file in full before making any changes. 2. **Study** the existing structure, tone, voice, and formatting patterns. 3. **Write** the requested changes with minimal diffs — targeted insertions over rewrites. 4. **Verify** the result by re-reading the full file to confirm coherence and that no content was lost.

Match the document's existing style. Every sentence earns its place.
