Poem

🐰 I nudged a word and hung a new view,
A hero swapped for something bright and new.
Context now dances where semantics stood,
A tiny image planted in the wood. ✨

⚠️ Potential issue | 🟡 Minor

Use descriptive alt text for the new diagrams.

At Line 33 and Line 67, alt="engine-architecture" / alt="with_wren_engine" are filename-like. Please use human-readable descriptions so screen readers convey meaning.
