For 16:9 (1280x720), vertical FOV is narrower than horizontal —
products could be clipped top/bottom. Now applies an aspect ratio
correction factor to camera distance: wider formats push camera
further back proportionally.
Still render (_blender_camera.py) already handled this via
min(fov_h, fov_v); cinematic now has equivalent correction.
