Cross-chain gas comparator: real, current gas price on Ethereum and Base side by side, wit

Cross-chain gas comparator: real, current gas price on Ethereum and Base side by side, with the delta and ratio between them, plus the estimated USD cost of a standard 21,000-gas transfer on each chain (using the live ETH/USD price). No advice or 'cheaper chain' verdict — just the numbers.
