### `geom.py` 的两条隐含约定

模块只负责 prism / roof / windows / bevel / building custom properties。
`roads.py` 是 road layer 装配模块，不拥有图层表或计数：
```python
def assemble_geojson_layer(path, layer_id, projector, collection, material, z): ...
def assemble_osm_fallback(ways, projector, collection, material): ...
```
`generate_scene.py` 仍负责创建 `road_mats`、调用 `catalog.check_layers()` 并打印
`Layer catalog warning:`、遍历 `catalog.ROAD_LAYERS`、维护 `road_counts`，以及写
`scene["road_feature_counts"]` / `SCENE_DONE["road_features"]`。模块只负责把已选定的
GeoJSON layer 或 OSM fallback ways 变成 `Road_<layer_id>` / `OSM_Road_<way_id>` 对象。
### 加一种新 OSM 要素
目标形态：**新增一个模块 + 注册一行，不改 `build()`**。
