  Noodle Tools shell.

  Same brand palette as Atlas (Moxxi blue + yellow, dark chrome over a light
  working area) so the two apps read as one family. Layout is "option A":
  the top bar carries the brand, the tool tabs and the account chip in one
  band; the active tool's sub-tools live in the dark sidebar beneath it.
