/* ---------------------------------------------------------------
   NightTrader — beginner's guide
   Loaded *after* site.css, which supplies the theme tokens, header,
   nav, footer and buttons. This file only adds the plain-English
   page's own layout: roomier measure, warmer surfaces, no monospace
   in the body copy.
   Every colour here comes from a site.css custom property, so light
   and dark parity is inherited rather than re-specified.
