Write a run of show for a webinar or all-hands meeting

Write a run of show for {{event}}, for everyone involved on the day: speakers, the host, and whoever runs the technology. They will keep it open during the session so that nobody has to ask what happens next, which means it has to be easy to follow at a glance.

Session details:
- Date, start time and time zone: {{date_time}}
- Total length: {{session_length}}
- Platform and tools (video platform, polls, chat, recording): {{platform}}
- Who is involved, and their roles: {{people}}

What has to happen, in rough order (segments, speakers, demos, questions, announcements):
"""
{{segments}}
"""

Produce:
1. A table with the columns Clock time, Duration, Segment, Who speaks, Behind the scenes (slides, polls, spotlight, recording), Cue to move on. Start 15 minutes before going live with a tech check, and end with the recording stopped and a note on what is sent out afterward. For example, one row in the form wanted: 10:58 | 2 min | Handover to demo | Host | Producer spotlights the demo lead and stops screen share | Host says the demo lead's name
2. Timing: durations from going live to the close that add up exactly to the total length, not counting the tech check, with the total shown under the table. If my segments do not fit, shorten the lowest-priority segment and say which, rather than running over.
3. Backup plans, one line each, for the common failures: a speaker's audio or video drops, slides will not share, a demo breaks, nobody asks a question, and the session runs long.
4. A short host script: the welcome (under 80 words), a one-sentence handover line for each speaker, and the close.

Use only the names, times and segments I gave. Do not invent speakers, job titles or content for a segment. If something the plan needs is missing, such as who presses record or whether questions are spoken or typed, put "[to decide]" in that cell and list every open point at the end.
