/* ============================================================================
   Collapsible sidebar: always-visible handle + collapse/drawer states.
   Driven by js/sidebar-toggle.js, which mirrors its state as classes on the
   <html> element (Blazor re-renders/reconnects replace the layout DOM but
   never touch <html>, so the classes survive):
     html.sidebar-collapsed   -> desktop: sidebar width animates to 0;
                                 mobile: the in-flow sidebar block is hidden.
     html.sidebar-drawer-open -> mobile only: the sidebar becomes a fixed
                                 full-height drawer overlay.
   These rules are NON-scoped on purpose (same convention as the nav
   scrollbar rules above): Blazor's CSS isolation cannot target classes on
   the <html> element, so they must live in this global stylesheet.
   Z-order: handle 950, drawer 940 - above the sticky .top-row (z-index 1),
   below #blazor-error-ui (1000) and .nav-scrollbar (1100). */
