/* =========================================================================
   styles.css — "security console" aesthetic on an MD3 token base.
   Dark-first, monospace accents, severity color coding. Pure CSS, no build.
   Non-card layouts: stat strips, feature rows, index lists, a stepper,
   numbered editorial lists, an accordion, and tables.
   shell.js depends on the chrome classes (appbar, gh-star, pagenav, navpill,
   footer, dialog, skip-link, icon-btn) — keep them styled.
