/* astaroa.com. One stylesheet, no framework.

   Colours are the palette proposed on HQ's logo page, with the pairs used for
   text measured against WCAG 2.2 AA (4.5:1 for text, 3:1 for large text and
   controls). Light: ink #12242F on paper #F7F5F1 is 14.6:1; links #0B7A70 on
   paper 4.8:1; secondary text #5B6B75 on paper 5.1:1. Dark: paper on ink is
   14.6:1; links #5ED2C5 on ink 8.7:1; secondary #A9B6BE on ink 7.7:1. The
   proposed accent #0E9B8E itself is 3.2:1 on paper, so it is used only where
   3:1 is enough: rules, focus rings and the rings beside the lead.

   The header, the lead and the page titles sit on a band of the ink colour
   in both schemes, with the dark pairs above. In dark mode the band is a
   deeper #0B1720 so that it still reads as a band against the page. */
