/* InsideOut London — Onboarding. Built on the IOL Interface system (screens), not the
   document system: dark by default, light is the same markup with tokens swapped.

   One deliberate departure from the console spec: this is a public, phone-first form
   filled in once, so there is no left rail, and type runs a step larger than the 13.5px
   console body. Inputs are 16px because iOS zooms anything smaller on focus. */
