/* aprs.now: the sister sites' look (aprsthursday.com, spaceaprs.com), with aprs.now's own
   raspberry where they have amber. Light by default; the dark look is space round the globe.
   The layout stamps the reader's choice on <html data-theme> before anything is drawn.

   Every colour on the site is one of these, so the two looks differ in this block and nowhere
   else. "-rgb" tokens are the three numbers of a colour, for rgba(var(--x-rgb), 0.1). --tint is
   the ink laid thinly over a ground: white on dark, slate on light. */
