/*
  Temp Side Menu Integrated CSS

  Collision-avoidance rules:
  - Every component class uses the unique glfm- prefix.
  - Menu selectors are scoped under .glfm-shell.
  - Flyout panels are positioned by temp_side_menu_integrated.js as fixed overlays
    so they are not clipped by a long/scrolling left rail.
