   Styled to sit in the same family as the platform's other front doors (Atmos's
   login card is the reference): a full-bleed gradient field with slow ambient
   motion behind it, one elevated card that rises into place, a generous logo
   lockup, a single full-width provider button, and the fine print set quietly
   below a hairline.

   What is *not* borrowed is the palette. Atmos is a blue daylight app with a
   white card; AssetForge is orange on graphite — the amber the app's mark, its
   buttons and its progress bars already use, over the same near-black the rest
   of the UI sits on. There is no second hue anywhere on this page: a cool cast
   in the background would read as another product's login wearing our badge.
   Same composition, same weights, same polish, one colour. */
