// Firebase adapter contract test.
// Runs the SAME storage contract as server (src/storage/contract.js)
// against createFirebaseStorage. The SDK is mocked via src/__mocks__/firebase/*,
// so this proves the adapter translates contract calls -> SDK calls correctly
// (path handling, merge semantics, subscribe, queryConstraints) without network.
//
// queryConstraints (orderBy + limit) now tested in shared contract for BOTH
// adapters — no separate firebase-only block needed here.
