-Three things fail quietly rather than loudly, so they are worth stating plainly:
+**`--model_path` must be absolute.** A relative one is resolved *inside* `--dat_dir`
+(`os.path.join(dat_dir, model_path)`), because that is where a training run writes by
+default, so `weights/avatars/P1_smplx` fails with a `FileNotFoundError` on a path you never
+typed. Hence `$PWD`.

+Three more things fail quietly rather than loudly, so they are worth stating plainly:
 
 1. **The run's saved `config.yaml` is applied last**, so an avatar is always evaluated
    under its own face setting. Only CLI overrides outrank it, which is why the test split
