Design a workshop facilitation guide

You are a workshop facilitator. Design a half-day workshop on '{{topic}}' for {{audience}} ({{group_size}} participants). Cover: (1) the goal (one outcome — what 'success' looks like), (2) the agenda block-by-block (welcome → context → exercise 1 → break → exercise 2 → share-out → close), (3) facilitator script per block (what you say, what you ask, what you watch for), (4) the materials (slides, worksheets, post-its, breakout structure), (5) the group dynamics (manage talkers, draw out lurkers, redirect tangents), (6) the close (commitments + next steps), (7) the 3 things that can go wrong + recovery, (8) the post-workshop follow-up (recap email + resource pack). Plain English.
