/*
  guide.css — the guide's own layout: the topic sidebar, the article, "On this
  page", previous/next, tables and notes. 2026-10-12, the site redesign
  ("Show It Running", workstream G): the one 17,000 px page became a page per
  topic.

  It reads only the tokens site.css defines on :root (--bg, --ink, --accent,
  --l-*, --f-*, --r-*, --measure …) and leaves the shared parts to site.css:
  .nav, .foot, .win, q.ui and kbd are styled there, never here.

  No left-border accents, anywhere (the owner's rule): a note is a tint with a
  small lamp dot, the current topic is a tint with a lit dot.
