 An engine's layout is rejected (scoring zero for that job) if any part falls outside the work area, any two parts are closer than the required spacing, or a drawing gets more parts placed than requested. A run that doesn't finish within its time budget also scores zero, as a timeout.

+Custom competitor engines can be added by dropping a DLL implementing `INestingEngine` with a public parameterless constructor into the `Engines/` directory next to the benchmark executable; each one is registered under its own CLR type name. This is a separate plugin contract from the desktop app's `NestEngineRegistry`/`NestEngineBase` (which requires a `(Plate)` constructor) — a `NestEngineBase` plugin dropped into the benchmark's `Engines/` folder is silently skipped, since the benchmark only ever solves whole jobs.
