   One stylesheet, organised top to bottom:

   1. Fonts           6. Hero               11. Contact
   2. Tokens          7. Section heads      12. Footer

   5. Buttons, nav   10. Skills             15. Motion: reveals, i18n, reduced motion

   Shape rule: interactive controls are pills (999px). Large surfaces use
   24px, media inside them 16px, small tags 8px.
