/* WP Exam Engine — public/frontend styles.
   Everything namespaced under .wpee- so it never fights the active
   theme (Section 62/63). Mobile-first: base rules are single-column,
   the sidebar layouts only kick in at wider viewports.

   Appearance is driven by CSS custom properties written from the
   plugin's Settings screen (see WPEE_Plugin::get_appearance_css). The
   fallbacks below mean the stylesheet still renders correctly if those
   properties are ever absent. */
