/* meshTerm docs: dark theme on meshTerm's own dark BrandColors.
   Plain CSS, no Sass, so GitHub Pages serves it as written.
   Structure and patterns follow the meshDeck docs site; colours come from
   MeshTermCore Branding.swift (dark set). Page bodies keep their historic
   markup, so the content classes below style that markup in place. */
