   Design tokens — computed from the viewport so that:
     * content caps at 1920px wide (centered beyond that),
     * the 5 inner columns stay ≤ 256px wide,
     * side margins grow up to 320px as space allows,
     * everything degrades smoothly down to 1024px.
   Use `100%` (not `100vw`) so the math resolves against body's
   content-box width, which is what `.site-header` / `.site-main` also
   measure against — `100vw` would include the scrollbar and drift the
   body::after overlay by the scrollbar width on Windows / "always
   show" macOS. Custom properties are text-substituted, so `100%`
   resolves in each consumer's context; for body::after that's body
   width, which is what we want.
