Reverted shell.css import on landing.html (its global `*` reset destroys
Tailwind layout). Instead: shell.js for component registration + inline
rstack-header CSS only. The standard header with logo, app-switcher,
MI bar, identity, and Try Demo now renders without breaking the page.

Serve the original Next.js rSpace-website (MySpace / (ou)rSpace
messaging) as the landing page at rspace.online/. Static export
copied into website/public/ so Vite includes it in dist/. Server
updated to serve landing.html at root with index.html fallback.
