A scene is an entry in the open registry LabScenes, shown on a plate: a flat lit disc, the package's own small sky with the sun at one hour, and a frame clock. Headless each camera (lab_shot, lab_shot_at) settles and is written as build/lab/<scene>/<shot>.png (a stored PNG, written here); in a window N and P step through them. tools/lab/run.sh and sheet.py make the contact sheet; tools/lab/plate_build.py makes plate/. ludic.render3d gains r3d_plate_mode (no terrain, grass or water is made) and r3d_sky_path. quit() in a program with no frame loop links. The example takes ~120 MB resident, 417 MiB peak footprint. Reseed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# setup builds what the scene shows and names its cameras (lab_shot); tick, if any, moves it each

# frame by the lab's fixed step; draw, if any, draws what is not an actor or a scatter layer.
