Auto-fixes (UP037, UP038, F401, I001, SIM105, RUF100) plus hand-fixes: drop the now-unused `Union` imports, annotate mutable class attributes with ClassVar, raise ValidationError instead of blind Exception in the zero-length test, delete two dead locals, and bind the per-iteration grid-builder closures to their loop variables (B023).
