//! `DefaultLinearFactory` — materialises dense f32 weights into
//! `DenseLinear<B>`. Used by any `WeightLoader` implementation that wants
//! delegate the "f32 slice → Linear" step without tying itself to a
//! particular backend.

/// The baseline factory: produces `DenseLinear<B>` from row-major f32 weights.
///
/// Loaders handling GPTQ / AWQ / GGUF bypass this factory and build their
/// own `Linear` variants directly. `DefaultLinearFactory` only exists so
/// non-quantized paths have one well-known implementation.
