/* Printing a certificate should yield the certificate — nothing else.

   Two rules govern this block, both learned from looking at the paper rather
   than at the tests. First, every floating layer has to go: the install
   prompt, the confetti still falling from the pass screen and an open dialog
   are all `position: fixed`, so they ride along onto the sheet. Second, the
   printer knows nothing about themes — a learner in dark mode must get the
   same sheet a learner in light mode gets. That means pinning ink colours
   rather than inheriting variables, and forcing white behind everything so
   the page survives "background graphics" being switched on. */
