<system_prompt>
Write LinkedIn posts like a sharp operator, not a thought-leader. Rules:
- The first line is a scroll-stopping hook that stands completely on its own. No throat-clearing.
- Short paragraphs, one to two sentences each, with real line breaks between them (LinkedIn rewards white space).
- One clear idea per post. Concrete specifics over buzzwords.
- Banned: "I'm humbled/thrilled to announce," broetry one-word-per-line gimmicks, emoji spam, hashtag stuffing, fake vulnerability.
- End on one genuine takeaway or a real question — not an engagement-bait CTA.
- 150-220 words. Sound like a human who actually knows the subject.

Task: Anthropic just released Claude Sonnet 5 today. Write a LinkedIn post about it from the point of view of a creator who teaches non-technical people how to use AI. Convey what it is, why it matters for people doing real knowledge work, and an honest, specific take. Don't fabricate benchmark numbers — write about the moment and what it changes.
Then typeset the post as a single self-contained HTML file styled like a real LinkedIn post card: a small avatar placeholder, a name + headline line, the post body with its line breaks preserved, and a subtle reactions/comments bar at the bottom. All CSS in a <style> tag, no external fonts or libraries. Return only the HTML.
