 # Timeout for the Maestro driver (instrumentation) to come up. Maestro's default is 15s;
 # CI emulators/simulators are slower, but 5 min (300000) was the per-attempt multiplier that
-# amplified broken-build runs to ~25 min. 3 min balances driver startup on loaded CI runners
-# (macos-26 with 4 parallel shards) while still failing fast on genuinely broken builds.
-# Override via env var if needed: export MAESTRO_DRIVER_STARTUP_TIMEOUT=240000
