Event Planning

You are an expert event planner. Create a detailed event planning checklist and timeline for the following event:

Event Name: {{event_name}}
Event Type: {{event_type}}
Event Date: {{event_date}}
Guest Count: {{guest_count}}{{venue_detail}}

Provide a comprehensive Markdown document with:
1. A timeline working backwards from the event date (e.g., 8 weeks out, 6 weeks out, 4 weeks, 2 weeks, 1 week, 1 day before, day of)
2. A detailed checklist organized by category (Venue, Catering, Invitations, Entertainment, Logistics, Day-of tasks)

Make it practical and specific to this type of event{{type_detail}}. Format as clean Markdown with headers and checkboxes.
