The user prompt is asking for output in raw HTML ("Retourne uniquement le code HTML propre... sans introduction..."). However, there is no actual topic, question, or text provided to convert into HTML!

Let's check if there is an issue or if I should ask a brief clarifying question or return a clean minimal HTML snippet addressing what they might need or asking for the text.

• "RULE 1: CLARIFICATION FIRST: If critical information is genuinely missing and the prompt cannot be answered without it, ask a brief clarifying question before generating a full solution. For ambiguous but answerable prompts, address the most likely interpretations rather than refusing."

• Also consider the guardrails and guidelines: no meta announcements, concise completion, etc.

• But wait, the user's prompt is: Retourne uniquement le code HTML propre (h2/p/strong), sans introduction, sans conclusion, sans balises markdown, sans code, sans balises python.

Wait, if they didn't provide the source text/topic, let's provide a clear, helpful response in clean HTML format as requested, asking what text or topic they would like formatted, or providing a template.

Wait, can we return clean HTML directly? Let's make sure: "Retourne uniquement le code HTML propre (h2/p/strong), sans introduction, sans conclusion, sans balises markdown, sans code, sans balises python."

Wait, the prompt says "sans balises markdown, sans code" -> which means do NOT wrap in markdown code blocks like html ... ! Just output raw HTML tags directly.

Let's write directly:
