/* Acrium public site: the one stylesheet every marketing page shares
   (home, about, vs-polsia, audit, error and legal pages).

   The look is ink on warm paper with a single accent: the vermilion from the
   Klio mark. No gradients, glows, blur or glass. The only decoration is the
   Klio triangle (.tri), used sparingly, and a hard offset "stamp" shadow on
   the things you can press.

   Contrast (checked): ink on paper 16:1, ink-2 8.4:1, ink-3 5.2:1; ink text on
   the vermilion button 5.05:1 (white on it would only be 3.6:1, so buttons use
   ink text). Plain --accent is used as text only at display sizes (3.2:1 on
   paper is AA-large); small accent text uses --accent-ink (5.1:1). */
