/* An icon in front of each top-level navigation entry. The icons are the
   theme's own Lucide set, copied into docs/images/nav-icons, and drawn as a
   mask in the text colour so they follow light and dark mode and the active
   state. The order matches the nav in zensical.toml. A section with an index
   page is a link, and a section without one (Reference) is a label, so both
   are matched. */
