  /* Desktop workspace height.
     The base rule caps the hub at 760px, so on a desktop screen the
     conversation list and the reading pane stayed short while the rest of the
     window sat empty. `.content` is a plain block whose height is derived from
     its children, so an earlier attempt at `flex: 1 1 auto` on the hub had
     nothing to grow into and collapsed it to its own min-height instead.
     Size the hub against the viewport directly: `.main` is the scroll
     container and fills the shell, and `.content` adds 32px/56px of padding,
     which is what the 104px subtraction covers. */
