description: Create or prettify a maatwebsite/excel export with proper headings, mapping, and styling.
argument-hint: <what to export>
---

Build/improve this export: **$ARGUMENTS**

Use the `excel-io` agent:
- Read the closest class in `app/Exports/` and match its style.
- Implement `WithHeadings` (French column titles), `WithMapping`, `ShouldAutoSize`, and `WithStyles` for a readable, formatted sheet.
- Pull data with eager-loaded relationships; avoid N+1.
- Respect RBAC — the export route must be permission-gated.
- For large datasets use `FromQuery` + chunking.

Add a Feature test asserting the download responds 200 with the expected headers/rows. Run pint. Report files changed + test result.
