   Dark panel in the site's own palette — cream on ink with orange
   accents, Barlow Condensed for the header. No backdrop blur: the
   page stays readable behind the scrim.

   The signature move is the entry. The panel's leading edge starts
   as a deep ellipse and straightens as it arrives, so it reads as
   liquid pulling across the screen rather than a box sliding in.
