     #4  .cta-btn              color:#f2a35c on #ffffff ≈ 2.2:1 contrast
     #5  .footer-inline-link   color:inherit (matches surrounding text);
                                text-decoration removed on :hover and
                                :focus so the only visual cue vanishes
                                on interaction
