/* Codivium cube component — canonical source of truth for the topbar 3D cube.
   Unlayered intentionally: must win over all @layer rules on every page.
   
   Compositing architecture:
   - .brand-mark: perspective container (no transform-style, no will-change, no filter)
   - .cube-wrap: 3D context (transform-style:preserve-3d, perspective here, NO filter/will-change)
   - .cube3d: the animated element (WAAPI runs here, will-change here)
   - .cube-face: individual faces (backface-visibility:hidden, translateZ)
   
   Drop-shadow lives on .brand-mark::after so it never touches the 3D rendering path.
