Generate a Run Sheet for a Small Birthday Gathering at Home

A small gathering at home still needs a plan, even if it is not a full event. This builds a timeline from the hour before guests arrive to the wind down, splits prep into the day before and day of, and flags one buffer point with what to drop first if the day runs long.

2. Include prep tasks that need to happen the day before versus the day of
3. Suggest one buffer point in case something runs late
4. Keep the plan realistic for a home gathering, not a full event production
