/* Site kit: header, buttons, the overview sections and the download page. Tokens live on :root so the header and
   footer read the same on every page; the .mx class adds the overview typography where a page opts in.

   Contrast: every token used for normal-size text clears 4.5:1 on the cream background (--mx-muted 6.1:1,
   --mx-brand-text 5.0:1, --mx-ink-2 9.6:1). The lighter brand terracotta (--mx-brand) is kept for large decorative
   areas, borders and hover states, never for small text. */
