/* academy.security.krd
   One design system with the monitor: same neutrals, same type, same
   spacing and motion. The difference is the accent — the monitor reads as
   a signal, the academy as the sun — so the two are recognisably one
   organisation without looking like the same page. */
/* Typefaces, served from this host.

   The academy was loading four families from fonts.googleapis.com while
   the monitor next door has served its own since the day it was measured:
   849 KB of font before a word appeared, and every reader's address handed
   to an advertising company as the price of opening the page. A site that
   teaches people not to leak their traffic to third parties should not
   charge them a third party to read the lesson.

   The files, the weights and the unicode ranges are the same ones
   pipeline/bake.py serves, deliberately: two deployments that disagree
   about what a typeface covers is a bug nobody would find for a year.
   All four families are SIL OFL 1.1 and each licence sits beside the
   files in assets/fonts/, as the licence requires.

   font-display:swap — the text arrives first and reflows when the face
   lands, which is the right trade on a slow connection. */
