ast.Num/node.n deprecated since Python 3.8; NodeVisitor falls back to visit_Num with a DeprecationWarning per dispatch. Under -W error this surfaced as a misleading fps ValueError in Video.init. Replace with visit_Constant, reject non-numeric constants, and pin parse results for int/fraction/float inputs in a regression test.
