We need to produce JSON with keys: summary (150-160 chars), category "howto", article_html containing full article in HTML. Must follow article rules: exactly one H1 at start with primary keyword. Primary keyword likely "best books to read for knowledge in hindi". H1 must contain that. Then H2 for 5-7 main sections. H3 for subsections. P tags: 2-3 per section, each 100-150 words. That is a lot of words: 1500+ words total. 5-7 sections with 2-3 paragraphs each. Let's aim for 6 H2 sections. Each paragraph 120 words. 3 paragraphs per section = 360 words per section. 6 sections = 2160 words. That's above 1500. Good. Need to maintain 100-150 words each. Must write 2-3 paragraphs per section. We'll have 3 paragraphs per section. Each paragraph 120-130 words. We'll approximate. Need to use UL/OL lists with 5-10 items. Include book recommendations with authors and key takeaways. Also end with 3-5 FAQ questions as H3. Also need to ensure only valid JSON (no markdown). The value article_html should be a string containing HTML code. Must escape quotes inside string? JSON string requires double quotes inside string escaped. We'll use single quotes inside HTML? But HTML uses double quotes for attributes. We'll need to escape them with \". Or we can use single quotes for attributes. But easier to escape double quotes. We'll produce article_html string with double quotes escaped. Also need to include meta description 150-160 chars. Let's craft summary: "Discover the top Hindi books that expand your knowledge across history, science, philosophy, and self‑growth. Dive into expert picks, authors, and key takeaways to boost learning." Count characters. Let's count: "Discover the top Hindi books that expand your knowledge across history, science, philosophy, and self‑growth. Dive into expert picks, authors, and key takeaways to boost learning."

Need 150-160. Let's shorten. We'll trim some words. Maybe: "Explore top Hindi books that broaden knowledge in history, science, philosophy, and self‑growth. Get expert picks, authors, and key takeaways to enhance learning." Count.

Good. Now article: H1 with primary keyword. Let's make H1: "Best Books to Read for Knowledge in Hindi". Good. H2 sections: maybe "1. Historical Insight Books", "2. Science & Technology", "3. Philosophy & Spirituality", "4. Self-Help & Personal Development", "5. Literature & Language Mastery", "6. Contemporary Thought & Modern Issues". That's 6 sections. Must use H2 for each. Within each H2, 2-3 paragraphs. Let's create 3 paragraphs per section. Paragraph 1: introduction to section topic. Paragraph 2: book recommendations with list UL/OL items. Paragraph 3: key takeaways and actionable insights. Need 100-150 words each. We'll approximate 120 words. We'll need to craft carefully. Also include book recommendations, authors, key takeaways. We'll need to list books with authors and highlight key takeaways. Make sure to use UL/OL lists 5-10 items. For each section, at least one list. List of books maybe 5 items. Also use STRONG tags for key terms. At end, after the 6 sections, include FAQ as H3 elements. 3-5 FAQ questions. We'll use H3 for each FAQ question and provide answer paragraph? The rule says "End with 3-5 FAQ questions as H3". So likely the H3 tags contain the question text. But need to provide answers? It says questions as H3. Might not need answers. But typical FAQ includes answer. But rule says "questions as H3". So just H3 tags with question. No further content? It's ambiguous. It probably expects H3 tags with question and following content? But rule: "End with 3-5 FAQ questions as H3". Could interpret that each FAQ question is an H3 heading. Not necessarily needing answer paragraphs. But we can include answer paragraphs or not. It's safer to include just questions, but maybe include answer paragraphs for completeness. But rule says "questions as H3". So maybe we only need H3 tags with question, no answer. Could be okay. We need to ensure article_html contains only valid HTML. We'll use wrapper? The article_html string should contain the article content. We can include

tags. But it's okay. We
