We need to produce JSON with fields: seo_title, summary, key_entities, expert_faq, internal_link_anchor, primary_keyword, secondary_keywords, content_type.

Constraints: 180-250 words total in summary. Must be 3-4 paragraphs separated by \n\n. Each paragraph 45-65 words (so total 135-195? Actually 3 paragraphs * 45-65 = 135-195; 4 paragraphs * 45-65 = 180-260. Need total 180-250, so likely 3 paragraphs of ~60-70 words each? But they said each paragraph 45-65 words. For 3 paragraphs, total 135-195, which may be below 180 minimum. So better to do 4 paragraphs each 45-65 => total 180-260, fits 180-250. So produce 4 paragraphs, each 45-65 words.

We need bold formatting: use double asterisks to bold a few key details, 3-5 total across summary. Bold only most newsworthy specifics: key company name, critical dollar figure, single most important fact. In this article, there is no company name, no dollar figure. The key fact: booting Linux kernel to host a single process in less than a second. Could bold "less than a second". Also maybe "Linux 6.8". Also "QEMU". Also "initrd". Choose maybe 3 bold terms: less than a second, Linux 6.8, QEMU. That's 3.

We must not bold generic words. Ensure bold only those.

We need to avoid banned words list: Additionally, align with, crucial, delve, emphasizing, enduring, enhance, fostering, garner, highlight, interplay, intricate, intricacies, key, landscape, pivotal, showcase, tapestry, testament, underscore, valuable, vibrant, nestled, groundbreaking, renowned, breathtaking, must-visit, stunning, profound, game-changer, robust, paradigm.

Also banned filler phrases: "in order to", "due to the fact that", etc. Avoid.

Also banned closers: can't end with future-looking platitudes. Must end with concrete statement.

We need to include key_entities: companies, people, locations mentioned in source. Source mentions: none? It mentions QEMU (not a company but a tool). It mentions Linux kernel, but not a company. It mentions KVM
