///
/// Like [`DeviceFeatures`](super::flags::DeviceFeatures), this mirrors a curated
/// subset of `wgpu::Limits` rather than every field wgpu exposes — the omitted
/// fields are mostly mesh-shader/ray-tracing-specific limits that pair with
/// `DeviceFeatures::MESH_SHADER`/`RAY_QUERY`, which aren't commonly needed
/// outside those features.
