- The `_NE` profile split is now tied back to the locomotive display census:
- `43` matched locomotive display-prefix families resolve `{internal_stem}_NE.imb`
- `18` matched display-prefix families still do not resolve `{internal_stem}_NE.imb`
- `0` unmatched display-tail families resolve `{internal_stem}_NE.imb`
- all `5` unmatched display-tail families (`242 A1`, `Class 460`, `Class A1`, `Class P8`,
`Class QJ`) are missing packaged `_NE` profiles
