   Concept: the logo's mark is a segmented ring — an aperture.
   The page is built around that single form: a slow, breathing
   core of concentric orbits, set against the exact navy sampled
   from the logo artwork (#021021) so the asset dissolves into
   the page. Ivory + a thin brass hairline replace the usual
   blue-glow tech palette.
