/*
  The generated wiki pages (docs/wiki/*.html, written by scripts/build-wiki.py).
  Shares the palette with the landing page through assets/tokens.css, and repeats
  its header, footer and base rules so the two read as one site.

  Layout is a sidebar plus a prose column. No decorative rails anywhere: nesting
  and hierarchy come from spacing, type scale and weight.
