   Loaded last. Adds the pieces that make the site something you work
   through rather than scroll past:
     · split hero with a live question card
     · "start where you are" role chooser
     · step-by-step explainers on every topic
     · outline-style sections that open on demand
     · "what is moving" reform timeline
     · category colour as a quiet wayfinding cue
   Same tokens as the rest of the system; no inline styles; every motion is
   switched off by the global prefers-reduced-motion rule in main.css.
