Could you build this?

Partial Wrapping existing libraries is common, but integrating a cutting-edge WebGPU compute-centric 2D vector renderer (Vello) into React's reconciler via WASM bindings requires non-trivial low-level graphics pipeline and reconciler plumbing.

What it would actually take: The implementation requires writing a custom React Reconciler (`react-reconciler`) in TypeScript that maps JSX declarative trees to scene graphs, bridged via WebAssembly (wasm-bindgen) to Rust. The hard part is managing asynchronous WebGPU device initialization, zero-copy buffer transfers between JS memory and WASM/WGPU, and synchronizing React render lifecycles with Vello's compute shader dispatch queue. It requires specialized knowledge of WebGPU compute pipelines, Rust WASM interop, and internal React reconciler architecture.
