/* ---------------------------------------------------------------------------
   zaSign public site.

   PLAIN CSS, NOT TAILWIND. The design reference uses the Tailwind CDN, which
   is a third-party script and is not allowed here. Compiling Tailwind at build
   time was the alternative; this file was chosen instead because the public
   site is a fixed, small set of components, so a utility framework would add a
   build step and a dependency for no benefit. Everything below is auditable in
   one place.

   CONTRAST. Every pairing used for text meets WCAG AA (4.5:1 body, 3:1 large
   text and UI borders). The figures are noted beside the tokens. Card borders
   are decorative and sit below 3:1 on purpose; anything that identifies a
   CONTROL (inputs, focus rings) uses --border-strong, which is 3.55:1.
