+- [ ] Do not schedule more than 90 minutes of continuous structured activity without a break
+- [ ] Do not close a workshop without capturing decisions and actions before the room empties — post-session follow-up is too late
+- [ ] Do not plan a workshop without considering psychological safety for sensitive topics — establish ground rules at the start
+- [ ] Do not underestimate timing — add 20% buffer to all activity estimates, especially for groups over 8 people
