Two-sided player-input trade arithmetic

This interactive two-sided row editor sums player-entered give and receive values. The working client-side editor reports both totals, the signed receive-minus-give difference, an optional percentage, validation, and the visible formula. Its neutral difference is arithmetic only; every result carries a no-market-verdict limitation.
