Return only one JSON object.
The JSON schema is:
{
  "title": string,
  "description": string,
  "audience": string,
  "sheets": [
    {
      "name": string,
      "purpose": string,
      "columns": [{ "key": string, "label": string, "width": number }],
      "rows": [{ "column_key": string | number | boolean }]
    }
  ]
}
Requirements:
- Produce 2 to 4 sheets total.
- Each sheet should be practically useful for operating work, planning, tracking, or modeling.
- Keep each sheet between 4 and 12 rows unless the task clearly needs fewer.
- Use concise column labels and concrete row values.
- Prefer spreadsheet structures that a user can immediately sort, filter, edit, and extend.
- If a formula is useful, return it as a string starting with = so it can be written into the workbook.
The likely use case is ticketing/event ops. Prefer sheets for sales/orders, attendee check-in, seating or inventory, and revenue summary.
