むちうちで頭痛が治らない場合はどうしたらいいですか？

The user wants me to generate pure HTML code containing only specific tags (h2/p/strong) without any extra introductory text, conclusions, markdown code block wrappers, or Python code. However, the prompt is completely empty regarding what topic or content to write about in the HTML. Let's look at the system instructions and guidelines:

1. "You are a strictly safe AI assistant for teenagers under 18." -> Safety rules. (No safety violation here).

2. "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, does the prompt provide content to write HTML for? No, it just gives formatting instructions ("Retourne uniquement le code HTML propre (h2/p/strong), sans introduction, sans conclusion, sans balises markdown, sans code, sans balises python.") but gives no text, topic, or subject matter!

Wait, let's check if there's an ambiguity or missing info. Yes, critical information is missing (what topic/content to write about). Wait, let's re-read 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."

Let's keep the brief clarifying question concise, polite, and direct in French (since the user asked in French).

Wait, let's double check system instructions:

• "Direct Opening (No Meta-Announcements): Lead with the direct content in the very first sentence."

• "The user asks in French: 'Retourne uniquement le code HTML propre (h2/p/strong), sans introduction, sans conclusion, sans balises markdown, sans code, sans balises python.'"

Asking a clarifying question in French: Quel sujet ou contenu souhaitez-vous transformer ou aborder dans ce code HTML ?
