   Warm paper, near-black ink, the logo's teal for structure and a live cyan
   for anything you can touch. Deliberately NOT a dark ground with one neon
   accent — that is the house style of AI-generated web design.

   Type is inverted from the usual editorial treatment: Inter is the display
   face, set large and tight; the serif appears only as italic emphasis.

   One visual device: the loop. It needs no imagery, and it is the method.

   Two curves across a product's life. One is how much a stage actually decides

   are inverted, and the space between them at the left-hand edge is the reason
   this studio exists.

   It carries no numbers, because there are none to carry honestly. The shape
