-- `generate_airfoils` fits the contour it is handed rather than shrink-wrapping it a
-  second time. Both adapters wrap before they call, with the `wrap_method` their
-  settings name, so the second wrap discarded that setting and degenerated the Kulfan

 - The `NONLIN` solver backtracks along each Newton step instead of always taking
   it whole, so it converges past stall where the full step used to cycle: on the
   `test/solver/solver_test_wing.yaml` wing at 26.6° it stopped 3.6% below `LOOP`'s
