## Usage Pattern

Configuration objects are passed to API functions like `nirs4all.run()`:

```python
from nirs4all.config.cache_config import CacheConfig

result = nirs4all.run(
    pipeline=pipeline,
    dataset=dataset,
    cache=CacheConfig(step_cache_enabled=True),
)
```

Most configurations are optional and use sensible defaults.
