/* --- Collapsible nav groups (Admin sidebar categories) ---
   Modeled on WordPress admin's own sidebar, not an original pattern:
   - The group containing the CURRENT page (.nav-group--active, set
     server-side — see $__navActiveGroup in sidebar.php) stays
     permanently expanded inline, no interaction needed, no toggle
     arrow — matches WP showing the active section's submenu open at
     all times while you're working within it.
   - Every other group shows just its label plus a right-pointing
     chevron by default. On hover (real mouse only, scoped via
     @media (hover: hover) so touch never gets a stuck phantom-hover
     flyout), its submenu appears as a flyout positioned to the right
     of the sidebar — overlapping the main content area rather than
     pushing the sidebar's own items down, exactly like WP's own
     flyout behavior.
   - Click/tap (.nav-group--expanded, toggled via JS) expands inline
     instead of a flyout — a side flyout doesn't make sense on a
     narrow mobile screen, so touch gets the same inline-push behavior
     the active group always has. */
