/*
 * Admin pages that use body.page-admin-settings (e.g. super-monitor) load style.css rules for a flex
 * .remoed-main. mobile-first.css (≥1025px) centers .remoed-content--readable with margin-left:auto,
 * which lets the fixed sidebar cover the main column until portal-sidebar-chrome runs.
 * This fallback keeps the readable column clear of the sidebar even if JS fails or is cached old.
