"""Model registry.

To add a new architecture:
  1. Create src/models/yourmodel.py with a class that:
       - accepts __init__(d_input, d_model, d_output, n_layers, **kwargs)
       - forward(x: Tensor[B, T, d_input]) → Tensor[B, T, d_output]
       - defines a static method  extra_kwargs(model_cfg) → dict
         returning any model-specific kwargs from the ModelConfig.
  2. Call  register("name", YourClass)  below.
