Why do USDC and USDT have different decimal precisions?

USDC natively uses 6 decimals across almost all networks ($1.00 = 1,000,000 units). USDT uses 6 decimals on Tron, Solana, and Ethereum, but certain legacy contracts or EVM variants implemented 18 decimals, requiring precise conversion before raw contract interactions.
