/* The shell: the places (Studio, Recordings, Settings) and the page beside them. Prefix pod-.

   Built from the smallest screen up. The shell is always exactly the window: the places hold
   still and the page scrolls on its own, so the studio can always fit the call to what's left,
   and nobody in a podcast is ever scrolled out of sight.
   - A phone, or any narrow window: the places in a bar across the top.
   - A phone on its side, or any short window: the places in a slim rail down the side, so the
     call keeps every bit of height.
   - A window both wide and tall enough: the places named, in a sidebar. */
