/* antisoftworks.com: AntiPDF's site, in the look of heimdall3d.com (the
   portfolio): system type, a calm paper palette in light and the night
   palette in dark, figures with a hairline border, sections that set text
   beside a picture and alternate sides.

   Theme: the visitor's system decides (prefers-color-scheme) until the
   header's sun/moon button picks one; theme.js keeps that choice on this
   device (data-theme on <html>). No other script, no third-party files. */
