// Nav items rendered in the middle column of the top nav, between the
// logo and the search bar. Exported so our custom header slot
// (`src/components/NavHeader`) can consume it; deliberately NOT
// passed via Fumadocs' `links` option, because that flow places text
// items on the far right of the header — we want the classic "Logo |
// Nav — — Search | Icons" layout (Tailwind / Next.js docs style) with
// the items aligned under the main content column.
//
// Icons chosen for semantic clarity + visual distinction at 16px:
//   Docs         → BookOpen      (reading reference material)
//   Guides       → Compass       (directional walkthroughs)
//   Tutorials    → GraduationCap (learning path)
//   Integrations → Blocks        (modular pluggable pieces)
//   Enterprise   → Building2     (organization / deployment)
//   Changelog    → History       (time-ordered records)
//   Blog         → Newspaper     (articles / posts)
