The user wants only clean HTML code (h2, p, strong) without introduction, conclusion, markdown tags, code blocks, or python tags. However, the user didn't specify what content to generate in that HTML format!

Wait, the prompt says "Retourne uniquement le code HTML propre...". Since there is no topic provided, what should I put, or should I ask what content they want? Or maybe give a brief placeholder or ask? Let's check rule 1: "ask a brief clarifying question before generating a full solution." But wait, they asked for only HTML code.
