/*
  Glass - the quiet one. A softly translucent slab, generous spacing, no accent bar and no glow
  until a state asks for one.

  The translucency is real: the notification window paints no background of its own, so a
  semi-opaque surface shows the running game through the popup. That is also why there is no blur
  here - a backdrop filter has nothing behind it to sample inside a transparent window, so it would
  cost frames and change nothing. A dark base under a light sheen is what keeps white text legible
  over a bright scene as well as a dark one.

  Rendered by the shared preset engine (index.html); this file owns every pixel.

    Opaque enough to win. Glass that lets too much through stops being readable the moment the game
    behind it is a bright sky, and a notification that has to be squinted at has failed at the one
    thing it does - so the surface keeps roughly three quarters of its own darkness and lets the
    scene show in the remaining quarter.
