/* =========================================================
   Resume — one A4 page, screen and print from the same markup
   Requires base.css (tokens, reset, type) and i18n.css

   Laid out in millimetres so the on-screen sheet and the printed
   page are the same object rather than two approximations of each
   other. Type is in px chosen to land on sensible point sizes:
   at 96dpi 12.6px prints as ~9.5pt.

   Single column on purpose. Applicant tracking systems extract text
   in document order, and a full-height sidebar interleaves with the
   main column and comes out scrambled. The one two-up block is at
   the end and each side is self-contained, so it extracts cleanly.
