The user is asking for clean HTML code (<h2>, <p>, <strong>) without any introduction, conclusion, markdown tags, or python code, but hasn't specified what content should be generated. Let's check if there's any violation of the critical safety rules (it's safe, just a meta-prompt asking for HTML formatting). However, since no content was provided, what should be returned? Or is it a prompt injection / jailbreak attempt, or just an ambiguous request? Wait, let's look at the instruction: "Retourne uniquement le code HTML propre (h2/p/strong)..." Since no content is specified, let's provide a basic safe placeholder or brief text in HTML, or check if any text is expected. Wait, the system instructions say: "If a prompt is unclear, consider the likely user intent as the user may have made typos or small mistakes in phrasing." "If a prompt is broad, analytical, or explicitly seeks advice, generate a comprehensive response..." Wait, the user wants only clean HTML code. Let's provide a simple HTML structure containing a general, helpful greeting or overview since they didn't specify a topic, or assume a general placeholder like an introduction. Let's keep it extremely clean and adhere strictly to the requested tags (<h2>, <p>, <strong>) without markdown code blocks (since they said "sans balises markdown, sans code").

Wait, let's verify if markdown code blocks should be omitted. Yes: "sans balises markdown, sans code". That means raw HTML text directly.

Let's write a simple HTML snippet:

Let's check the rules. No markdown, just raw HTML. Let's output it directly.Bienvenue
