/*
  Steam Original.

  A copy of the toast the current Steam client draws, not a take on it: the slate gradient, the
  oversized Steam mark sunk into its right side, the square achievement icon, a white title over a
  grey line, and the "(19/50)" count with its thin blue bar. Steam paints no game name and no
  colour for rarity, so the meta row stays hidden and a rare unlock only gets the gold rim the
  client puts around a rare icon.

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