Look up the current owner of one ERC-721 token on Base with ownerOf(uint256). Accepts a strict contract address and uint256 decimal token ID, performs one read-only eth_call with bounded public-RPC fallback, and returns the normalized owner address. Reverts, non-contracts, nonexistent tokens, malformed responses, and upstream failures return non-2xx and do not settle.
