/* ============================================================================
   ANIMA NAVIGATION MENU
   ----------------------------------------------------------------------------
   Hamburger toggle (top-right) + slide-in panel from the right. Replaces the
   scattered per-scene top-right buttons; built scene-aware in menu.js. Styled
   as a dark glass panel so it reads over both the dark EigenSpace and the light
   Modal Studio backgrounds.
