//! Weight-format abstraction for Ferrum models.
//!
//! Separates "what is the weight matrix like" (dense f32, GPTQ int4, AWQ,
//! GGUF, ...) from "what device does the math" (Backend) and "how does the
//! model wire things together" (model code).
//!
//! Usage in model code:
//! ```ignore
//! let qkv: Box<dyn Linear<B>> = loader.load_linear("model.layers.0.self_attn.qkv_proj")?;
//! qkv.forward(ctx, &input, &mut out, m);
//! ```
//!
//! The `Linear` trait dispatches to the appropriate backend kernel
//! (`B::gemm` for Dense, `B::gemm_gptq` for GPTQ, etc.) without the model
//! having to branch on quantization type.
