/* The Voice dock: voice to notes (voice.js).

   A flow of three steps — 1 Take, 2 Shape, 3 Add to song — laid out by the
   room the dock gives it (container queries, not the window: the side
   panels and the on-screen piano decide the dock's size):
   - wide, or short (a phone on its side, the desktop's default dock): the
     three steps side by side, each scrolling on its own;
   - medium: Take on the left, Shape beside it, Add to song under Shape;
   - narrow (a phone): one column, in order.
   The panel scrolls whenever its content is taller than the dock (a
   container query styles only what is inside the container). */
