/* Hero cube: a native CSS 3D sculpture. Keep filters/opacity off the preserve-3d chain.
   The cube itself is a brand object (it carries the wordmark), so like the logo it is NOT themed:
   its palette lives in the --cube-* tokens below and stays the same in every site theme.
   Everything around it (halo, status, buttons) uses the site tokens. */
