   InstantNode Docs — rebuilt from scratch on the public site's design system
   (v2/css/lunaris.css). Same tokens, type and aesthetic as instantnode.eu, so
   the docs read as part of the marketing site. Injected by server.js, which
   strips each page's old inline <style> so this is the ONE stylesheet in play.
