+This script completely replaces the "Boilerplate Chatbot" with a Generative UI (The "Poetry Workshop").
+
+It implements the "Mad Libs" style interface we discussed:
+
+Dropdowns for Format and Persona (Hardcoded constraints).
+
+Free Text for the Topic (User agency).
+
+No Chat History: It focuses on a single, high-quality output.
