   hero.css — full-height hero: copy on the left, console panel on the right

   Layout mirrors the reference's 60/40 split. The backdrop is generated in
   CSS: a slow-drifting blue aurora, a masked dot field, and a veil that
   guarantees text contrast. Content enters in a stagger via .ds-hero-enter,
   with each block's offset, blur and delay set inline in the markup.
