   "MCAT Prep Mockups" Claude Design canvas exactly. Two token layers,
   composed in the same order the mockup itself used:
     1. The imported "Modernist" design system's own base tokens/components

     2. The mockup page's own <style> override (fonts, accent colors).
   Everything here lives under `.app2` (set on <body>) so nothing above
   (the classic quiz.html page, its own --bg/--ink/etc. tokens) is affected.
