The user didn't specify the exact content they want inside the HTML, but they requested only clean HTML code (<h2>, <p>, <strong>), with no introduction, no conclusion, no markdown code blocks (), and no other wrappers.

Let's assume a generic clean block 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 says "Retourne uniquement le code HTML propre... sans introduction, sans conclusion". If I ask a question, I violate the "uniquement le code HTML" constraint. Let's provide a well-structured HTML snippet using <h2>, <p>, and <strong>.

Wait, what content? Let's make it a clean, professional section about clean HTML or a placeholder, or maybe a brief statement. Let's keep it minimal and compliant.
