/* =============================================================
   pfizer-prototype.css — the four-screen medical inquiry prototype.
   Two layers:
     .pf-*  the portfolio frame around the prototype (dark, Neue Montreal),
            so it reads as part of the site.
     .px-*  the product itself, in the round-two Pfizer identity (light,
            Noto Sans). These are the tokens the Patterns screen documents;
            change one here and update that screen to match.
   The canvas is designed at 1440px and scaled with `zoom` in
   pfizer-prototype.js, so every screen keeps its designed proportions.
