  Full-screen constellation hero, matching the docs landing page. Loads the
  shared landing design system (homepage.css) instead of app.css and suppresses
  the base sticky nav so the hero owns the screen. The animated polar-bear
  constellation is injected into .constellation-bg by bear-constellation.js.
