/*
 * site-sub.css: the house header and footer for the standalone account pages
 * (konto-neu.html, konto-reset.html). 26.09.2026.
 *
 * Why a separate file: those two pages carry their own inline styles on
 * purpose (someone who is locked out must reach them even if the main
 * stylesheet fails), and css/preview-professional.css would bring global
 * rules for body, h1, a and .button-primary that fight the inline card. The
 * owner wants the home page header on every page, so this file holds ONLY
 * the header and footer rules, copied from css/preview-professional.css and
 * css/site-controls.css (both unchanged) and scoped to .site-header,
 * .mobile-nav and .site-footer. Keep them in step with those two files.
 *
 * The header is marked data-frame="standalone"; js/account.js runs its burger
 * menu and the scrolled backdrop there.
