   BLEND HERO ANIMATION  (see token-bound.html -> .tb-blend)

   Two neon talking heads (brand orange + brand blue) that drift together and

   Built with the exact animation language of the Re-Production Studio intro
   card (wz-welcome-card in flow.css): a rotating neon conic edge, a drifting
   grid, floating glows, a scan line, an animated equalizer and a pulsing live
   dot. Pure CSS (no JS) so it is cheap and never fights the card renderer.
