/*
    Desktop: UI shell.

    Drives the real desktop.html and asserts the visible shell works in
    every major aspect a user touches:

      - wallpaper layer + task bar render
      - the taskbar clock shows a real time
      - the quick-access panel carries the user's identity + storage bar
      - the start (list) menu opens, lists modules, and its search box
        filters the module list (and reports "No Result" for gibberish)
      - the notification bar toggles from the clock
      - a desktop shortcut created via the API renders as a launch icon

    Window management and context menus have their own spec (023).
