The user wants only clean HTML code (using <h2>, <p>, <strong>), with no introduction, no conclusion, no markdown code blocks, and no python tags.

Wait, the prompt itself is just asking for HTML formatting rules in French ("Retourne uniquement le code HTML propre..."), but doesn't specify what content to put inside the HTML tags.

Let's check the rules:

• Concise completion / direct response.

• No markdown code blocks (meaning don't use html ... , just output the raw HTML directly if that's what's requested, or a simple placeholder/example since no topic was given).

• Wait, since no topic was given, what should be inside the HTML? Let's provide a basic clean HTML structure matching the requested tags (<h2>, <p>, <strong>) about a generic helpful topic, or leave it minimal, but wait, the prompt says "Retourne uniquement le code HTML propre (h2/p/strong)".

Let's write a simple example using those exact tags without any markdown formatting wrappers.

<h2>Titre Principal</h2>
<p>Ceci est un paragraphe contenant du texte <strong>important</strong> pour illustrer la demande.</p>

Wait, the user said "sans balises markdown" (no markdown tags). If I output raw HTML, should I avoid markdown code blocks? Yes, "sans balises markdown, sans code". So I should just output the literal HTML text directly without any backticks.
