   Orbital docs — ONE BASE: the Orbital app.
   Every colour, radius, blur and shadow below is the app's own value, taken
   from /root/orbital-app/src/index.css and tailwind.config.js:
     glass      backdrop-blur-xl bg-white/5 border-white/10
     hover      border-purple-500/30 bg-white/10
     glow-sm    0 0 10px 2px rgba(147,51,234,.2)
     base       #0a0618
     font       Satoshi (Fontshare, same URL the app loads)
   Layout is GitBook's: left nav tree, breadcrumbs, on-page TOC, prev/next.
