Monster Robot Party 4bcd7b49d9 LANE7: four workplaces, built from data 
Office.gd is gone. Floorplan.gd consumes a spec Dictionary — bounds, palette, walls
with doors and glazing styles, window runs with mullions and blinds, ceiling style,
light grid and style, slabs, static props, desk clusters, chairs, level-specific
smashables and spawn — and Levels.gd holds four of them.

Making this data rather than four subclasses means a site is authorable in minutes,
levels can be diffed, and a real generator can later emit the same structure (a BSP
split of the footprint -> rooms -> doors on shared walls -> fittings by room type).
That was the actual answer to "can we use this git to generate plans": the repo John
found is OpenSCAD SVG->STL for 3D printing, with no generation, no plan parsing, no
room polygons and GPL-3.0, so it can't help — but Office.gd was already most of a
parametric plan builder, and lifting its numbers out is the real path.

The four sites are deliberately not reskins; they differ in the three things a player
actually reads — palette, light, and what the walls are made of:

  SCRANTON      magnolia, grey carpet, drop ceiling, fluorescent troffers, daylight
                down one glazed wall. The baseline.
  PAWNEE        civic beige and blue-grey, low partitions everywhere, a public
                counter, pinboards. Municipal and over-partitioned.
  THE INCUBATOR timber floor, white walls, 3 m ceiling, PENDANT lights, glass wall
                onto a pool. Nobody has an office; they work at a dining table.
  SUB-LEVEL 4   concrete, NO windows at all, exposed services, bare strip lights, a
                wall of server racks. The light is green and everything is junk.

L cycles sites in-game; _load_level tears down the shell, rebuilds, re-registers task
stations and re-arms the shift.

tools/gen_level_props.py adds ten more procedural props. The filing cabinet is the
important one: it exports as a CARCASS plus a separate DRAWER, each with its own
floor-centre origin, so the Gauntlet can pull a drawer out as its own rigid body and
spill the files. Also file folder, desk phone, guillotine, shredder, server rack,
sofa, wastebin, stapler.

dev/probe_levels.gd builds every level and reports residual motion after a full
second. All four read 0.00 m/s.

"""Second batch of procedural props: the ones the Gauntlet and the three new workplaces
need that a box can't fake.
Same rule as tools/gen_office_props.py — if it IS a box (counters, partitions, tables,
whiteboards) it gets built in code by the level builder. This file is only for silhouettes.
/Applications/Blender.app/Contents/MacOS/Blender --background \
--python tools/gen_level_props.py -- [--render]
Convention: glTF Y-up, 1 unit = 1 m, ORIGIN AT FLOOR-CENTRE, so a level can drop a prop
at a floor position with no offset maths. In Blender that means authoring Z-up with the
base on z = 0.
The cabinet is the exception and the important one: it exports as a CARCASS plus four
separate DRAWER meshes, each with its own origin at its own floor-centre, so the Gauntlet
can pull a drawer out as its own rigid body and spill the files inside it.
