JDK 17, iOS simulator runtimes. The real gaps are: CocoaPods (for Flutter iOS), no Android system image / AVD (needed to launch an Android
  emulator), and the build env's PATH. Let me kick off the big download (Android system image) in the background and check the CocoaPods path in
  parallel:

  Ran 1 shell command 

● System image is downloading. Ruby is 2.6 (system), so I'll pin CocoaPods 1.11.3 (last version supporting Ruby 2.6) for Flutter iOS. Let me start
  that install in the background too, and watch the Android download:

  Ran 1 shell command 

● Android system image installed (3.8 GB system.img in place). Now create an AVD, launch a headless emulator (so it runs cleanly over SSH), wait for
  boot, and grab the screen via adb screencap — that's the dev-loop feedback I need:

  Ran 1 shell command 

● Android emulator booted in ~18s (Android 15), emulator-5554 online, screen captured. Let me look at it:

  Read 1 file, ran 1 shell command 

● Screen's black — the emulator booted but the display is asleep (normal for a headless boot). Let me wake it, dismiss the keyguard, go to the
  launcher, and re-capture:

● Running 1 shell command…
