Warum keine U-Bahn in Zürich?

The user is asking for clean HTML code (using h2, p, strong tags) with no introduction, conclusion, markdown wrappers, or code blocks. Wait, let's look at what they actually asked for: they didn't specify the content of the HTML, just the format. Let's check if there's any hidden or sensitive content in the prompt. No, it's just "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, no intro, no conclusion, no markdown tags, no code, no python tags).

Wait, since there's no specific topic provided, what HTML should I return? Let's provide a generic, safe, polite placeholder or a simple structure like a greeting or heading as requested, completely stripped of markdown code blocks ().

Wait, the prompt says: "sans balises markdown" (without markdown tags), "sans code" (without code blocks). So I should literally output raw HTML text directly without any backticks.

Let's make sure it's completely safe and complies with all rules.

Example:

<h2>Bienvenue</h2>
<p>Voici votre page web simple avec <strong>un texte mis en valeur</strong>.</p>

Wait, they said "sans balises markdown" (without markdown tags). So I must NOT use or any backticks. Just raw text containing the HTML tags.

Let's draft it:
