You are an Astra Blender worker for Forge. Build a PACK of street and canal pieces for "Hop City", our browser game in the
Crossy Road class (three.js): a small city animal hops across roads, tram lines and canals, one grid cell (2 m) per hop.
The game camera is high behind the hero, about 55 degrees down; a 2 m cell is 50 to 90 px wide on a phone. Look at
city-look.png in this directory with your image tool first: that is the city (semi-realistic textured buildings, real
cars, grey streets). Your pieces must sit naturally in it: realistic but readable, a little toy-like and clean.

STOP TIME: 20:57 CET (18:57 UTC) (check `TZ=Europe/Paris date` between models). At the stop time, finish the model in
hand, write the lineup and NOTES.md, and end. Deliver each model as soon as it is done (I integrate them while you work on
the next).

Blender 5.2 is headless on another machine. Write bpy scripts here and run them with:
  timeout 600 ssh gex44 /root/blender-spike/blender-5.2.0-linux-x64/blender -b --python-exit-code 1 --python /root/hop-street/<script>.py
(first `ssh gex44 mkdir -p /root/hop-street`; scp scripts there, scp renders and GLBs back here, then LOOK at the renders with
your image tool). One Blender process from you at a time. Wrap every ssh/scp in `timeout`. Never touch other /root dirs.

PIECES (in this order; sizes in metres, width (x) x length (z) x height (y)):
1. street-sweeper, 2.0 x 5.0 x 2.7: municipal street sweeper truck, bright ORANGE cab and body, white side stripe (plain,
   no text), big round side brushes under the front corners (dark bristles), amber roof beacon (Glow), hopper box behind
   the cab. It is the game's chaser: it rolls in from behind and sweeps up a hero who dawdles. Make it characterful.
2. tram, 2.3 x 16.0 x 3.3: modern city tram, two linked sections, CREAM body with a bold TEAL roof and lower skirt, big
   windows (Glass), pantograph on the roof, headlights (Glow) at both ends. It crosses the screen at speed on tram lines.
3. raft-2, raft-3, raft-4 (three models): floating wooden canal rafts made of planks lashed across two or three logs or
   barrels, 1.8 m wide (z) and 4.0 / 6.0 / 8.0 m long (x, the long axis is X for these three, they drift sideways), 0.45 m
   high, warm wood, a rope coil or a crate on the longer ones. Heroes ride them across the canal.
4. lily-pad, 1.7 x 1.7 x 0.12: a big flat canal lily pad with the classic notch and one pink flower near the edge. A static
   stepping spot on the water.
5. donut, 0.55 x 0.55 x 0.22: a ring doughnut with PINK icing and colourful sprinkles; the game's collectible snack. Lying
   flat, readable from above.
6. tram-signal, 0.5 x 0.4 x 2.6: tram crossing signal: a dark post, a black panel with two round red lamps side by side
   (Glow, one material "Glow" for both lamps), a small bell on top. Faces +Z.
7. bench, 1.8 x 0.7 x 0.9: park bench, dark green metal frame, warm wood slats.
8. hedge, 1.8 x 1.8 x 1.3: rounded trimmed park shrub in a low stone kerb, rich green leaves.

LOOK
- Real proportions, bevelled edges, real thickness, the details that shape the silhouette. Smooth shading on round parts.
  No flat untextured grey.
- Readable from above: each piece has ONE strong identity colour on its top surfaces.
- Materials: simple PBR. Either CC0 Poly Haven textures (https://dl.polyhaven.org/file/ph-assets/Textures/jpg/1k/<id>/<id>_<map>_1k.jpg,
  maps diff, nor_gl, arm) or procedural node detail, BAKED with Cycles into ONE texture set per piece so it survives glTF
  export; flat-colour materials are fine for small parts. List Poly Haven ids in NOTES.md. No other image sources.
  Original generic designs: no text, no logos, no brand names, no real company colour schemes.

GAME CONTRACT (hard, every piece)
- One GLB per piece: <slug>.glb, glTF binary, +Y up, metres, origin at the CENTRE OF THE FOOTPRINT ON THE GROUND (y = 0 at
  the lowest point), front facing +Z (rafts: long axis X). Apply all transforms and modifiers. Join everything into ONE mesh
  object.
- At most 4 materials: "Body" (opaque, optional base colour + ORM + normal textures, each at most 512 px), optional extra
  flat-colour opaque materials, optional "Glass" (alpha blend, no texture, alpha about 0.35), optional "Glow" (emissive
  colour, no texture).
- Triangles: donut, lily-pad at most 1200; bench, hedge, tram-signal at most 2000; rafts at most 2500; street-sweeper at
  most 5000; tram at most 7000. GLB at most 600 KB each (tram 900 KB). No cameras, lights, empties or armatures in the GLB.

DELIVER in this directory, per piece: <slug>.glb, <slug>.png (800x800 Cycles render, the GAME view: camera 55 degrees down,
3/4, soft daylight, grey asphalt or canal water ground, a 2 m grid square outlined faintly for scale), <slug>-side.png
(800x800, side view). Also build_street.py (ONE script that builds every piece from an empty scene and exports them; the
GLBs must come from a clean run of it), lineup.png (1600x800, all pieces, same game view), street.json ([{slug, glb,
size_m:[w,d,h], tris, materials:[...]}]), NOTES.md (per piece one line: what, tris, colour; then what still looks weak).
Before delivering each GLB, re-import it in a fresh Blender scene and check: origin on the ground centre, size within 10
percent of the size above, material names, triangle count. Fix and re-export if anything is off.
Stop when every piece is delivered or at the stop time.
