/* KESTREL-9 marketing landing (SPEC addendum §A7).
   Loaded ONLY by landing.html. Everything is scoped under body.lp-body or
   the .lp- prefix so none of it can reach the authenticated app.

   The landing deliberately pins its own dark cinematic palette instead of
   reading theme tokens: it is a fixed piece of art sitting over a starfield,
   and a visitor who once picked the light theme must not get white panels
   over black space. The app behind /register is fully themed as before. */
