Found by the first runtime capture of the grade: a capture has no avatar, so
CurrentArea stayed None and no zone was ever graded; and the day/night weight
read WorldTime (the server clock, noon offline), so a manual/capture night
graded with the day LUT. Adds CaptureCameraArea (area under the camera, only
under WOW_CAPTURE, never read by the area authority) and grades by the
rendered GameClock minute. LIGHTING.md notes the preset/capture changes.
