Static SPA over UP33 (ve(3,3)) + the official Uniswap v2/v3 deployments: browse and add liquidity across all three, manage CL/v2 positions, one-token ZAP adds, aggregator vs native swaps, and LP-based limit orders. Ships with a zero-dependency pool indexer for uniswap discovery. Browser-wallet signing only; no key material anywhere.
