Sun-fog strength 0.25 / angle 0.4 / lean 0.4, end-fog lean 0.25: the first
pass turned dusk ridges into flat orange cut-outs against a blue sky. The
dome's low band now MIXES toward the far fog colour by 15 deg (an offset
over-pushed an already warm dusk ring). update_fog_model joins the
ordering test's ALLOWED list (it runs in the resolve set, after it).
