/* W4-D4 (#241) — the docs site's one stylesheet: light and dark from the
   reader's system setting, readable line lengths.
   Design v2 (the Web-Docs board, docs/design/SPEC.md): midnight text,
   tomato-700 links, mist bands and code, the public site's header and
   footer; on dark, night with tomato-400 links and the butter focus ring.
   The system fonts stand in for the board's, so the site loads nothing
   from another host. */
