A smaller aircraft example that still runs a complete mission.
The change
I reduced the advanced single-aisle example to a generic 42-input FLOPS aircraft deck, updated the beginner documentation, and added an end-to-end mission regression test.
The result
The reported minimum-aircraft run converged with SLSQP in 12 iterations for a 1,906 nmi mission. The merged example is a starting point, not a calibration to a particular aircraft.
