/* Atlas brand, taken from the Atlas home page on lynks.ba (lynks-site/src/index.css):
   navy + cyan, one family (Sora), sentence case, left aligned. Cyan marks only what you can
   act on and your own question; gold marks only an answer without a source.

   WCAG AAA, computed against the real backgrounds (navy, navy-2, navy-3), not eyeballed:
   every text colour is >= 7:1 (mist 12.6+, slate 7.4+, cyan 7.2+, gold 7.5+, danger 7.3+),
   field and control borders are >= 3:1 (--field-line 3.1+), every target is >= 44x44 px
   except citation numbers inside a sentence. Change a value, re-check it before shipping. */
