# Runs the Maestro E2E suite for apps/user-ui — Android only.
#
#   - loads secrets/defaults from the gitignored e2e/.env (Maestro has no .env support)
#   - always passes --platform android, so it can never target an iOS simulator
#   - falls back to ~/.maestro/bin/maestro when `maestro` isn't on PATH
#
# Usage:
#   bash e2e/run.sh                               # all flows
#   bash e2e/run.sh flows/place-order.yaml        # a single flow
#   bash e2e/run.sh --device emulator-5554        # target a specific emulator
#   bash e2e/run.sh --format junit                # extra Maestro flags pass through
