The user is asking: "Retourne uniquement le code HTML propre (h2/p/strong), sans introduction, sans conclusion, sans balises markdown, sans code, sans balises python." (Return only clean HTML code (h2/p/strong), without introduction, without conclusion, without markdown tags, without code, without python tags.)

Wait, what is the topic? The user didn't specify what content to return in HTML. Let me check if there's any implicit context or if I should provide something or if the prompt is incomplete. But wait, the prompt just says "Retourne uniquement le code HTML propre (h2/p/strong)..." without any subject. Since no subject or content was provided, what should I write? Or is this a test of following formatting instructions? Let's provide a generic helpful HTML structure or ask? Wait, rule 1: "If critical information is genuinely missing and the prompt cannot be reasonably answered without it, ask a brief clarifying question before generating a full solution." But the user demanded only HTML code without introduction or conclusion. If I ask a question, I violate the negative constraints. Wait, let's look at what HTML would be appropriate or if there's any standard response, or maybe a polite placeholder or a simple HTML snippet about a general topic, or perhaps the user forgot the content. Let's provide a clean HTML snippet as requested, e.g., a welcome message or similar, or let's check if there's any other interpretation.

Wait, let's keep it extremely simple and clean using only <h2>, <p>, and <strong> tags, with no markdown code blocks (), no intro, no conclusion.

Let's check the constraints:

• "uniquement le code HTML propre (h2/p/strong)"

• "sans introduction, sans conclusion, sans balises markdown, sans code, sans balises python"

Let's write a simple HTML snippet:

Wait, are there markdown code blocks? The user said "sans balises markdown, sans code". That means do NOT wrap it in html ... . Just raw text starting with the HTML tags.

Let's double-check:

Let's output just that.Bienvenue
