/* ORBIT · Studio — a playable by laousmail.
   The instrument fills the screen: the canvas draws the sound, the ring of
   pads plays it, and the ring doubles as a circular timeline when looping.
   The studio dock sits at the bottom: transport always visible, panels
   behind tabs. Labels use a small mono face. */
