/*
 * IRClass Academy homepage — header + hero (Phase 2).
 *
 * Loaded ONLY on the frontpage (see theme/edash/layout/frontpage_irclass.php).
 * Every rule is scoped under body.irclass-home so nothing here can affect
 * login, dashboard, course, or any other eDash page.
 *
 * Ported from the approved static prototype's styles.css. Font: the
 * prototype specifies "Inter", loaded there via Google Fonts CDN. No local
 * copy of Inter exists as a reusable theme asset in this installation (the
 * only local Inter files found belong to H5P's bundled library, an
 * unrelated subsystem, and are not a safe/stable thing for the theme to
 * depend on), and no external CDN dependency was introduced here per
 * instructions. Falling back to the prototype's own fallback stack
 * (Arial/sans-serif) until Inter is sourced and self-hosted properly.
