/*
 * ChangeIP: WHMCS 9's cart CSS dropped the white background on the section
 * headings ("Choose Account", "Payment Details") and expects the Twenty-One
 * theme's .primary-bg-color to supply it. cip-six-custom doesn't define it, so
 * the divider line ran through the heading text. WHMCS loads this file after
 * all.min.css and keeps it across updates.
