Adds an Optimize button to the composer that rewrites a one-line idea into a structured product brief: a positioning sentence, 3–6 key features, visual references and design tokens; it sits beside your original text in a compare dialog where you can accept it into the input, generate another version, or cancel and keep the draft untouched. No settings page and no API keys — it calls the model channel you already configured.
