BFS Sigmas Preview
Shows a sigma schedule: the noise level at the start of each step and how many steps fall on layout / identity (high noise), shapes and detail (low noise). With H3's video shift of 12 most steps sit at the top; lowering the shift moves steps toward detail. Changes nothing: sigmas pass through.
