/* The studio: the shell, the app bar, the three ways in (draw, upload, text), the
   output column with its previews, settings, files and code, and the status bar - one
   section per part of the page. Only the shell pages (the studio and /not-found) load it.

   Breakpoints, written at 1.2x because of the root scale (see app.css):
     1228.8px  the two halves go side by side and the shell owns the viewport
      599.98px phones: the root scale drops to 100% (app.css)
   Inside the studio and the output, container queries decide the rest, so each part
   lays itself out by the room it actually has rather than by the window. */
