  // visible/hidden-track-opacity:
  // The hidden and visible track represent whichever track is visible or
  // hidden in the ui. This could be the .mdc-switch__track :before or
  // :after depending on whether the switch is selected or unselected.
  //
  // The m2 slide-toggle uses transforms to hide & show the tracks while
  // the m3 slide-toggle uses opacity.

  // These tokens have always been empty for M3, but these token values should be used
  // (with the same technique of calling `elevation.get-box-shadow`)
  // Currently, internal users have M2 tokens being applied by accident
  // handle-elevation-shadow: map.get($system, level0),
  // disabled-handle-elevation-shadow: map.get($system, level0),
