/* Responsive */

/* ---------- Responsive: mobile page navigation ---------- */
/*
  Below the breakpoint, the three areas (workspace rail, section list, editor)
  stop being a permanent 3-column layout and become pages you navigate between:

  - "list" (default): section list fills the screen, rail is off-screen to the left
  - "list" + peeked: rail slides in partway, list shrinks to stay visible alongside it
  - "editor": editor fills the entire screen, rail and list are both off-screen

  This is done by giving .app a flex track wider than the viewport and sliding it
  with translateX, rather than toggling display - so the transition is a real slide,
  not a cut.
