fix(cinema): lift brightness so the 4 depth systems don't stack to black

Browse source 
near-fade × fog × DOF × seam-fade each multiply a <1 factor; together they were
crushing the figure dark. Raised the fog floor (0.18→0.45) and the color/emissive
glow bases so the stacked attenuation lands in a vivid range. Verified live.
