Pipelines
A pipeline runs a list of steps in order, feeding each step's result into the next as its input. It is how you compose the simple types into something powerful — normalise, then map, then format.

| Field | Description |
|---|---|
| steps | The ordered list of transforms. The first step usually names its input; later steps omit input and receive the previous result. |

Step by step: the department is trimmed of whitespace, upper-cased, and the clean value is looked up to an OU — with a fallback if it is not in the table. Any step can itself be a nested transform, so pipelines and the other composite types combine freely (up to the 20-level depth limit).
