+### Threlte BufferGeometry Pattern
+
+**NEVER use `T.BufferAttribute` with `args` array** — in Vite 8 production builds this causes a `byteLength` crash.
+
+**Use `T.BufferGeometry oncreate` instead** to set buffer attributes and compute normals:
+
+```svelte
+import { BufferAttribute } from 'three';
+
+const setupGeometry = (geo: BufferGeometry) => {
+  geo.setAttribute('position', new BufferAttribute(vertices, 3));
+  geo.computeVertexNormals();
+};
+// ...
+<T.BufferGeometry oncreate={setupGeometry} />
+```
+
+See `Mesh3DScene.svelte` for the canonical example.
