/*
  B166ER — shared styles for every page.

  Three layers, back to front:
  1. The backdrop: one huge word per chapter (the product's name), set in Clash Display. It sits *behind* the
     particle field, so the shapes pass in front of the type. Its letters rise out of a blur as the chapter
     arrives, and a slow light runs across them in the product's colour.
  2. The particle field (transparent canvas).
  3. The foreground: as few words as possible, in Satoshi.
