/* ===========================================================================
   Midly site chrome: palette, nav, mobile panel, buttons and footer.

   Shared by every page. The homepage links it with site.css (base type) and
   home.css; the older pages link it after their own inline styles, followed
   by legacy-theme.css, which maps their colour tokens onto this palette.
   Everything here is class-scoped so it cannot restyle a page's content.
