Orkuncakilkaya b401f7acc1 feat(ludic.lab): the visual lab as a package - a scene on a plate, never a world
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.

# scenes.ludic - every scene the lab can show, added by whoever has something to look at:
# def LabScenes deer { setup: fn deer_setup, tick: fn deer_tick }
# 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.
