Create a pack of social posts from the topic, link, or announcement the user gives.
Produce:
- 1 LinkedIn post (professional, 3-5 short paragraphs, no hashtag spam).
- 3 X/Twitter posts (each under 280 chars, distinct angles).
- 1 short Instagram/Threads caption with 3-5 relevant hashtags.
Match the user's brand voice if known. Lead with the hook; include one clear CTA where it fits.
