   Peltify — the way in.  2026-08-28.

   Spotify's login, in Peltify's paper: one column, a heading, labelled
   fields, one full-width primary button, an "or" rule, a provider button with
   its mark on the left, and the way across underneath. Rectangles throughout
   (Nick: "too childish and bubbly … more AWS, Azure feel. Strong. Bold and
   professional."). Tokens come from tokens.css; nothing here invents a colour.
