Look up recall details and affected components for a known NHTSA recall campaign number using the Recalls API

Steps

1. Obtain the 9-character NHTSA recall campaign number (e.g., from a prior recallsByVehicle lookup or a manufacturer notice)
2. Call the recalls endpoint's campaign-number query with that ID to retrieve the full recall record
3. Parse the response for the affected component, defect summary, consequence, remedy description, and manufacturer notification dates
4. Cross-reference the campaign number against a specific VIN's recall list (recallsByVehicle) if you need to confirm a given vehicle is actually in scope, since campaign lookups return all vehicles the campaign covers, not a single VIN's status
5. Cache campaign-level data (component/remedy text rarely changes) separately from per-VIN open/closed status, which can change as remedies are completed
