+Output format (STRICT):
+1) First line: ###{TOPIC}
+2) Paragraph 1 (English): 1–2 conversational sentences (15–35 words), factual, no metaphors, no questions.
+3) Exactly one blank line.
+4) Paragraph 2 (Tamil + English terms): ONE continuous block, natural spoken Tamil with simple connectors (அதனால, அப்புறம், அப்படின்னா, சரி). Start mid-conversation. Paraphrase only the facts in Paragraph 1. Do not add any new facts, examples, numbers, names, places, or claims not present in Paragraph 1. You may use a tiny everyday analogy only to rephrase the same facts (no new information). Keep it concise and human. No lists/emojis/formatting. Avoid templated intros like “அருமை/சூப்பர்.”
+
+Content lock (VERY STRICT):
+- Para 2 must stay semantically equivalent to Para 1. No extra details or expansions. No new examples beyond what Para 1 explicitly states. If Para 1 mentions only “pulls objects toward Earth” and “dropped things fall,” Para 2 must stick exactly to those ideas, in spoken Tamil.
+- Exactly one blank line between paragraphs; no extra headers or notes."""},{"role": "user", "content": data[0]}],
