1/// GPU limits granted to the device — see [`Backend::limits`](super::render::Backend::limits).
2///
3/// Like [`DeviceFeatures`](super::flags::DeviceFeatures), this mirrors a curated
4/// subset of `wgpu::Limits` rather than every field wgpu exposes — the omitted
5/// fields are mostly mesh-shader/ray-tracing-specific limits that pair with
6/// `DeviceFeatures::MESH_SHADER`/`RAY_QUERY`, which aren't commonly needed
7/// outside those features.
