Turn the Breton granite fisherman's house you built earlier into a reusable KIT of pieces ("atoms") for Forge's asset
library, so a code assembler can build MANY different houses from the same pieces and the same shared materials.
Look at final.png and sheet.jpg here (the house), and read build_breton-stone-house.py (your earlier script). The earlier
remote work dir with its downloaded CC0 Poly Haven textures and baked material swatches is gex44:/root/fal-author/
breton-stone-house-v1/ (textures/, baked/): reuse it, do not change it.

Blender 5.2 is headless on another machine. Write bpy scripts here and run them with:
  ssh gex44 /root/blender-spike/blender-5.2.0-linux-x64/blender -b --python-exit-code 1 --python /root/fal-author/breton-atom-kit-v1/<script>.py
(first `ssh gex44 mkdir -p /root/fal-author/breton-atom-kit-v1`, scp scripts there, scp results back here, LOOK at the
renders with your image tool). Only one Blender job at a time from you.

THE SHARED MATERIAL SHELF (same 8 materials as the house, same names exactly): Granite_lime_moss, Dressed_granite,
Blue_grey_slate, Breton_blue_timber, Aged_ivory_frames, Weathered_zinc_iron, Old_window_glass, Terracotta.
Deliver materials/<Name>/{BaseColor,Normal,ORM}.png (TILEABLE, seamless, 1024 px; glass/zinc/frames/terracotta may be
512) and materials/Granite_lime_moss/Height.png (the rubble relief height the walls are displaced by, same tiling as its
BaseColor, 1024, 16-bit or 8-bit grey, 0 = mortar depth). materials.json: for each material its tile size in metres
(one texture repeat), roughness/metalness factors if any, and for Granite_lime_moss the displacement scale and bias in
metres (your script used .105 and .006 with a 2.25 m repeat) and how the moss/wet lower zone is represented (prefer: it
is baked into a second material Granite_lime_moss_base for the lowest 0.9 m, or explain the UV rule).

UV RULE FOR EVERY ATOM: UVs are world-scale: u, v = metres along the surface / that material's tile size, so any atom
placed anywhere shows the shared textures at their true scale. No per-atom unique textures, no texture images inside the
atom GLB at all (the game binds the shelf by material name).

THE ATOMS: ONE file kit.glb, each atom a separate top-level mesh node named EXACTLY as below, transforms applied, origin
as stated, Y up, +Z = outward from the facade (toward the street), X along the facade, metres. Real construction detail
as in the house (bevels, proud jambs, drip sills, glazing bars, plank grooves, slate chips): this kit must look as good as
the house. Triangle budget per atom in brackets.
- slate_a, slate_b, slate_c: one roof slate 0.345 wide (X) x 0.42 long, 0.012 thick, slightly different chipped corners,
  lying flat in the XZ plane, its TOP edge on z = 0 and the slate extending toward +Z (down the slope); origin at the
  middle of the top edge. [<= 40 each]
- ridge_tile: terracotta ridge cap 0.42 long along X covering a ridge whose two roof planes meet at the pitch of the house
  (about 44 degrees); origin on the ridge line at the tile centre. [<= 120]
- quoin_long (0.60 x 0.386 high x 0.35 deep) and quoin_short (0.35 x 0.386 x 0.65): dressed granite corner blocks,
  origin at the block centre, the long face along X. [<= 150 each]
- window_ground: a complete window unit for a 0.95 m wide x 1.30 m high opening in a 0.38 m thick wall: proud granite
  jambs, drip sill, lintel, reveal faces lining the opening into the wall (to z = -0.38), ivory timber frame, casements,
  glazing bars, glass. Origin at the bottom centre of the OPENING on the wall's outer face plane (z = 0); the wall
  generator cuts a 0.95 x 1.30 hole there. [<= 3000]  window_ground_shutters: the same plus open blue plank shutters.
- window_upper: same for a 0.85 x 1.10 opening; window_upper_shutters: with shutters. window_small: 0.50 x 0.70 gable
  window. [<= 3000 each]
- door: granite surround, blue planked door as a SEPARATE child mesh named door_leaf hinged on its left edge (its origin
  on the hinge line), one granite step proud in front; for a 1.00 x 2.10 opening; origin at the bottom centre of the
  opening on the outer face plane. [<= 4000]
- dormer: a complete dormer (dressed stone or timber cheeks, front with window_upper-like window and small iron rail,
  its own small slate roof and terracotta ridge, 1.3 m wide) that sits on a 44 degree main roof; origin at the bottom
  centre of the dormer front face, y = 0 = the main wall's eaves height, z = 0 = the main wall's outer face. [<= 8000]
- chimney_stack: gable chimney 1.00 (X) x 0.70 (Z), 2.0 m high from its origin at the bottom centre, dressed granite with
  a cap course and two terracotta pots on top. [<= 2500]
- gutter_1m: half-round zinc gutter 1.0 m along X with two brackets; origin at the middle of its back top edge (that edge
  fixes under the eaves). [<= 250]  downpipe_1m: round zinc pipe 1.0 m along Y with one wall bracket; origin at the bottom,
  on the wall face. [<= 150]
- eaves_board_1m: timber fascia 1.0 m along X; verge_board_1m: barge board 1.0 m along X that the assembler rotates up
  the gable slope; both origin at the middle of their top back edge. [<= 60 each]
- lantern: the wall lantern; origin at the wall mount point on the face. [<= 600]

Also deliver: kit.json (every atom: node name, bounding box, origin rule, the opening size it expects where relevant,
triangles, materials used); kit_sheet.png (1920x1080 Cycles render of all atoms laid out in a row with names on a light
grey floor, textured with the shelf); build_kit.py (ONE script that builds kit.glb + materials from scratch, the
delivered files must come from a clean run of it); NOTES.md (6 lines: what you made, triangles, materials, texture
sizes, Poly Haven ids, what differs from the house).
Stop when every atom matches the detail of the house and the shelf textures tile seamlessly.
