Added datasheet-derived electrical types and descriptions to all 289 terminals. Final classifications: 175 bidirectional, 37 power inputs, 37 grounds, 18 inputs, 15 outputs, 5 power outputs, and 2 not-connected reserved pins.
- Verification: 289/289 descriptions populated; no unspecified or unsupported types.
- ERC note: No ERC records are generated for this standalone, netless part project; classifications were independently audited instead.
- Open items: None.
