The showcase: agentic work, entirely on Quest.

 Run the Codex desktop app inside the local Linux environment. Point, right-click, type with a virtual or Bluetooth keyboard, dictate through the Quest microphone, work with Git, and build Android apps on the headset.

 Inkscape, camera import and local printing are also validated.
