Why do I need a PPS number in Ireland?

The user's prompt is empty or incomplete (it only specifies formatting instructions: "Retourne uniquement le code HTML propre..."). Wait, looking closely at the prompt: "Retourne uniquement le code HTML propre (h2/p/strong), sans introduction, sans conclusion, sans balises markdown, sans code, sans balises python." But what content should be in the HTML? There is no subject specified.

Let's check Rule 1: "CLARIFICATION FIRST. 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."

Wait, the prompt says "Retourne uniquement le code HTML propre...", but gives no topic. Let's ask a brief clarifying question, but wait, the user requested only HTML without introduction. However, since the topic is completely missing, I need to know what HTML to generate. Let's keep it extremely brief and helpful.De quel sujet souhaitez-vous que le code HTML traite ?
