We need to write an SEO article about best books to read in Hindi for free. Must return JSON with keys: summary, category, article_html. Article must be HTML. Must follow article rules: Exactly one H1 at the start with primary keyword. So H1: "Best Books to Read in Hindi Free" (primary keyword). H2 for 5-7 main sections. Each section has 2-3 P tags, each 100-150 words. So each paragraph 100-150 words. That means each section has 200-450 words. There are 5-7 sections. That would be 1000-3150 words. Minimum 1500 words. So we need at least 5 sections. 5 sections * 200-450 words = 1000-2250 words. So we need at least 1500, so we can do 5 sections of 400-500 words each. But each paragraph 100-150 words. So 2 paragraphs per section: 200-300 words. 5 sections = 1000-1500. For 1500, we need each paragraph ~150 words. 2 paragraphs per section -> 300 words each section. 5 sections = 1500 words. That meets min. But we also need 3-5 FAQ H3 at end. That adds extra words but not counted? Should be okay. We'll produce around 1700 words. We must include specific book recommendations, authors, key takeaways. Must use UL/OL lists with 5-10 items. Use STRONG for key terms. Let's outline sections: H2 sections (5): 1. "Digital Libraries and E-Book Platforms" - talk about Project Gutenberg India, Hindi e-books, etc. Provide list. 2. "Classic Hindi Literature You Can Access for Free" - list of classics like "Gita", "Ramcharitmanas", "Premchand's stories", etc. 3. "Modern Hindi Fiction and Contemporary Reads" - recent authors and free releases. 4. "Non-Fiction and Educational Resources" - self-help, history, science free books. 5. "Tips for Finding and Downloading Hindi Books Legally" - guidelines, how to use public domain, etc. Then FAQ H3. Each section: 2-3 paragraphs of 100-150 words. Let's aim 2 paragraphs (~120 words each) = 240 words per section. 5 sections = 1200 words. Add FAQ maybe 300 words. Total ~1500. Good. Paragraph length: 100-150 words. We must count roughly. We can approximate. Let's craft each paragraph. Paragraph 1 of section 1: 120 words. Paragraph 2 of section 1: 120 words. Similarly for others. We need to include UL/OL lists of 5-10 items. Probably in each section. Use STRONG tags for key terms. Use H3 for subsections maybe within sections. We could have H3 for each bullet list maybe? But we can just use UL. H3 can be used for subsections like "Top 5 Platforms". So within section 1 we can have H3 "Top 5 Platforms to Access Hindi Books for Free". Then UL. That counts as a subsection. We must ensure exactly one H1 at start. H2 for 5-7 main sections. H3 for subsections. We'll have H3 for each list. Also FAQ H3 at end. Let's start. We need to produce JSON with keys. We must ensure article_html is a string containing the HTML. We need to escape quotes? But JSON string will contain quotes escaped. The assistant must output JSON, so we can just output raw JSON with double quotes around string. The article_html string must contain HTML with proper escaping? In JSON, we need to escape double quotes inside string. But we can avoid double quotes inside HTML by using single quotes for attributes? But we can use double quotes in HTML but then need to escape them. Safer to use single quotes in HTML attributes or no attributes. We'll just avoid attributes that use double quotes. But we can use double quotes for tag names? Tag names don't use quotes. We can use text content with no quotes. So no problem. But we might need to include & for ampersand. Implement article_html string with newline escapes? We can include literal newlines. JSON string can have newlines. That is okay. The assistant must output JSON object. We'll produce: { "summary": "...", "category": "howto", "article_html": "

... " } Need to ensure JSON is valid. We'll include newline characters as actual newlines. That's allowed. But ensure no stray control characters. Let's write content. Paragraph counts: We'll approximate. Let's craft paragraphs. Section 1: Paragraph 1: 120 words. Let's write: "With the rise of digital archives, Hindi readers now have unprecedented access to a vast library of free literature. From religious scriptures to modern novels, most of these works are available in PDF, ePub, or online reading formats. The primary advantage of digital platforms is that they often host public‑domain titles, meaning they are fully legal to download and share. In addition, several universities and cultural institutions have digitized their collections, making them available to the public at zero cost. For anyone seeking Hindi books without spending a dime, exploring these resources is the first logical step."
