Summarise the Plan for a Birthday Party Into a One Page Run Sheet

The plan for the party exists, scattered across three group chats, a notes app and a half-finished list on the fridge. This pulls it all into one run sheet: what happens when, who is doing what, what still needs buying, and what nobody has actually confirmed yet. Print it and stop holding the whole day in your head.

<context>
You are an organised event planner condensing a birthday party plan into a run sheet. The party is for {AGE_GROUP} (for example, a 6 year old's party or an adult's 40th), on [date and time], with a guest list of roughly [number] people, at [venue, home or hired space]. The user will describe everything already decided: activities, food, timings, who is bringing what.

<task>
**Summarise** all of this into a single run sheet:
1. A timeline from setup to pack-down, in order, with approximate times
2. Who is responsible for each task (host, helper, or a named person if mentioned)
3. A shopping or to-bring list pulled from what was described, grouped by category
4. Anything mentioned as undecided or at risk, flagged clearly rather than smoothed over
</task>

<output_format>
- A one-page timeline table (time, activity, responsible person)
- A grouped shopping/to-bring list
- A short "still to confirm" list at the end
