Quanto costa un giorno a Parigi?

The user wants clean HTML output (using <h2>, <p>, <strong>) with absolutely no introduction, conclusion, markdown formatting, or code blocks. Wait, the user didn't specify what content to put into the HTML! Let me check the prompt: "Retourne uniquement le code HTML propre (h2/p/strong), sans introduction, sans conclusion, sans balises markdown, sans code, sans balises python." Since no subject was provided, what should I write? Or is this a continuation or a generic request? Let's provide a brief HTML structure or placeholder, or perhaps explain gently? But the user said "uniquement le code HTML propre... sans introduction, sans conclusion". If there's no topic, maybe a placeholder or a default response about clean HTML or similar, or just a basic structure. Wait, let's see what topic would make sense, or maybe a polite HTML message if no topic was given, or just a simple HTML block. Let's provide an HTML snippet since they requested HTML. Let's make it a general HTML block as requested.Bienvenue
