/* ==========================================================================
   Virta — stylesheet
   --------------------------------------------------------------------------
   Tokens first, then layout primitives, then components. No frameworks, no
   third-party CDNs: the fonts are self-hosted so a visitor's browser makes
   zero requests off-site (that matters when your pitch is data sovereignty).

   Brand palette carried over from the legacy skin (includes/layout-content.css
   and the header artwork) so the site still reads as Virta:
     navy   #07206F  legacy heading / link colour  -> the spine
     orange #E74618  legacy navigation accent      -> the single accent
     blue   #1B5EB9  sampled from the logo band
     green  #3FA96B  sampled from the logo band

   Contrast: #E74618 only ever carries LARGE display text or decoration.
   Anything small and orange uses --accent-ink (#C93A11, 5.1:1 on white) or
   white-on-orange buttons, which also use --accent-ink. Verified by hand.
