/proc/cyborg_animation_frames	Authored anchor data is generated offline; runtime never scans marker pixels.
/proc/cyborg_animation_anchor	Returns the still frame a chassis's parts are placed against in this direction and pose, or null when it has no authored animation
/proc/cyborg_animation_map	One pixel per native frame, encoding a literal anchor translation after part transforms. Only catalog descriptors reach this cache; player colors and placement are not cache keys.
