   One stylesheet. Mobile first. Light and dark.

   Colour contrast is checked, not guessed:
     light body  #1b1b1f on #fbfbfc   16.2:1
     light dim   #5c5c66 on #fbfbfc    6.4:1
     light link  #c4382d on #fbfbfc    5.1:1
     light btn   #ffffff on #d93a31    4.6:1
     dark  body  #f0f0f3 on #111113   17.4:1
     dark  dim   #a0a0aa on #111113    7.3:1
     dark  link  #ff7a73 on #111113    7.4:1
     dark  btn   #17171a on #ff5f57    6.0:1

   #ff5f57 is the brand red, Apple's close-button colour. It is too light to
   carry white text on a white page, so light mode uses a darkened version for
   anything interactive and keeps the true red for the mark itself.
