Locks in the recent NaN/zero-radius/zero-falloff guards: - inner radius returns full influence (1.0) - at/beyond outer radius returns 0 - rim falls off as 1 - t² (smooth) - NaN/inf distance rejected (returns 0, not 1 from short-circuit) - zero/negative/NaN radius rejected - zero falloff produces hard-edge brush
