/* MiTax - legal.css
   Page styles for the LEGAL / TRUST surfaces:
   privacy.html, terms.html, ndpa.html, security.html.

   Built on the shared design system (tokens.css + base.css +
   components.css). This file only adds the legal-document
   typography system + a few security-page helpers. No new palette
   colours - brand tokens only (#0357ED primary / #11BD8F accent). */
