// AMM UI test — create a NEW pool (A/C) through the Liquidity view.
//
// Drives the running AMM UI through the QML inspector (logos-qt-mcp), the same
// way swap.mjs does. It selects the A/C pair (which the setup script leaves
// UNSEEDED — only A/B is created), lets the form auto-fill the minimum opening
// deposit, submits the create, and verifies the pool now exists ON-CHAIN.
//
// Prereqs in the running app (see apps/amm/tests/README.md):
//   * launched against the isolated test wallet + TOKENS_CONFIG that
//     testnet/setup-amm-testnet.sh writes (TKA, TKB, TKC)
//   * an open wallet + reachable local sequencer
//   * the A/C pool must NOT exist yet (setup only seeds A/B)
