/* sstich.ch stylesheet
   Named site.css (not style.css) so it can live next to the old page's
   stylesheet on the server without overwriting it. */

/* Light only, on purpose.

   Every colour is a token in the :root block below, so swapping the palette
   means replacing that block (plus deleting the header-band section further
   down, if you want the band gone). The alternate palette is written out in
   README.md.

   The palette here is the one the previous sstich.ch used: the #b3b5e4
   lavender band behind the header, #f8f6ff tints, and navy #003355 links.

   To follow the visitor's OS theme, add a @media (prefers-color-scheme: dark)
   block redefining these same tokens. */
