   Luntrack landing page — what a logged-OUT visitor sees at luntrack.com.
   Signed-in visitors never reach it: index.html's init() goes straight to the
   app, exactly as before.

   Everything here is namespaced under .lp- so it cannot collide with the app
   shell that lives in the same document. Colours come from theme.css tokens,
   so the landing restyles itself along with the rest of the site.
