  IMPORTANT
  ---------
  This stylesheet intentionally supports TWO class naming schemes.

  A previous version used:
    .appShell / .sidebar / .rightbar / .btnSide / .filterInput / .btnClear / .fab

  The current index.php uses:
    .layout / .side / .right / .sideBtn / .filter / .clearBtn / .gearFab

  To avoid changing any PHP/HTML/JS, we alias selectors so BOTH work.
