Build a fleet management web app for a small fleet operator.

1. Vehicles: plate, VIN, make, model, year, current odometer (number, required), assigned driver, status (active, in service, retired).
2. Drivers: name, phone, email, license number, license expiry, assigned vehicle.
3. Maintenance schedules: per vehicle, intervals in miles and months for oil, tires, brakes, annual inspection and registration. Compute a due date and due odometer from the last service.
4. Service log: vehicle, date, odometer, vendor, work performed, cost, days out of service, receipt photo upload.
5. Fuel log: vehicle, date, gallons, price per gallon, total, odometer (number, required), station.
6. CSV import for fuel card exports, mapping date, gallons, total and odometer, rejecting any row without an odometer.
7. Dashboard: vehicles due for service in the next 30 days, overdue services, and cost per mile per vehicle computed from fuel, service and repair spend divided by miles driven.
8. Reminders: email the manager and the assigned driver 14 days and 3 days before a service is due, and immediately when a service goes overdue.
9. Daily vehicle check form for drivers: odometer, lights, tires, fluid warning lights, notes, photo.
10. Reports: monthly cost per vehicle, total spend by category, downtime days per vehicle.

Design: clean operations dashboard with a cream background and a deep blue accent, large readable numbers, mobile friendly for drivers, and a strict keyboard-only path for logging fuel in under 15 seconds.
