   battle-pass.css: /battle-pass/, the Fortnite terminal.
   The site as a Battle Pass: every page a reward tier, graded by
   rarity, unlocked as you go. The rarity colors are the five the
   genre has used since long before Fortnite (gray, green, blue,
   purple, gold); no logo, wordmark or asset is reproduced, and
   every tile is drawn with CSS.
