Steadier hull lighting when the camera turns

We fixed a lighting bug in Shattered Rift where turning the camera could wrongly brighten an entire hull. Under the old lighting, hulls visibly changed as the camera rotated; now the edge lighting holds steady. The first screenshot is from the combat camera, and the others compare the old and corrected lighting in controlled test scenes. Existing hulls, faction colors, hit flashes and status effects are preserved. Hull and detail art, and sustained performance, still need work.
