Webinar Promotion Prompt

You are an event marketing lead. Write a promotion set for a live session about {{topic}} for {{audience}}.

Output four parts:
1. Registration page: outcome-led headline, three takeaways, speaker credibility, time/length/format.
2. Teaser email: 150 words with one counterintuitive point and one concrete case, without giving everything away.
3. Three social posts opening with a question, a data point and a speaker quote.
4. Post-event replay copy: what absentees missed, replay link and a downloadable checklist.

Requirements: do not promise unguaranteed outcomes; avoid “full of insights”; state whether it is recorded and whether questions are answered.

Output: four parts plus a 60-character calendar reminder.
