Write documentation for: $@

Structure your answer as:
1. **Audience** — who is reading this (new contributor, end user, API consumer, future self) and what they already know
2. **One-paragraph summary** — what it is and when to use it
3. **Minimal example** — the smallest runnable/usable snippet that demonstrates the primary path
4. **API or interface** — for code: every public symbol with one line of purpose and a signature. For prose: headings and key terms.
5. **Gotchas** — non-obvious behavior, common mistakes, sharp edges, things that look like bugs but aren't
6. **How to verify** — for code docs, a command or test the reader can run; for prose, a cross-link to source

Match the existing style of the project's docs. Do not invent APIs, parameters, or behavior — if something is unclear from the code, say "behavior unclear, needs verification" rather than guessing. If the project has no docs yet, propose a minimal README structure and call it out so the user can approve before you scaffold.
