/* fixvis docs (/docs/*): three-column reading layout, built by scripts/docs-build.ts.
   Colours come only from tokens.css (light and [data-theme="dark"]); this file never names a hex.
   Layout per the docs developer guide §5: 260px sidebar, 760px article, 220px "On this page"
   at >= 1200px; the right rail drops below 1200px; the sidebar becomes a drawer below 900px.
   Classes are prefixed d- so nothing collides with site.css. */
