   site.css — layout and components for the one-page portfolio.
   Replaces the purchased template (Bootstrap + style/responsive/theme/
   components.css). Colours and fonts come from tokens.css, so the light and
   dark themes share every rule here.

   Breakpoints: 900px (two columns → one, nav collapses), 600px (phones).
