Blacklight.WinForms is the WinForms host for Blacklight: the drop-in ViewportControl that hands a window
handle to the active graphics backend, plus the input plumbing around it (the WinFormsInput shim that
translates WinForms events into IInputConsumer calls, mouse-wheel forwarding, and message mocking for tests).

It is deliberately thin and platform-specific.  The camera "gameplay" lives in Blacklight.Core; this module
only bridges WinForms input and hosting to it.
