   landing.css - Scapewatch marketing landing page.

   Styles extracted and adapted from the game's login screen
   (client/css/style.css, the .login-* and .patch-notes-* rules).
   Layout changes from the login screen:
     - logo at roughly half size, pinned toward the top
     - three stacked play buttons in the center
     - extra text links (Wiki / Guide / Map / Presskit) top-left
