   blur washes: the page is line-art and type, and the motion does the
   talking. Every animated state is gated on `.js`, so the document

   back. A reveal that never fires is therefore visible, not blank.
   The `to` keyframe lands on `transform: none` on purpose: a held
   transform would become the containing block for `.tl__meta`'s
   sticky positioning and pin the dates to the page.
