/* =========================================================================
   MarinovOS — boot.css
   Lives in os/. The wallpaper URL below is relative to this file.

   Scope: everything is prefixed #bootOverlay, .boot- or html[data-startup].
   Motion: only opacity and transform are animated. Wallpaper blur is static
   and fades away with its layer, rather than recalculating a blur each frame.
   The cursor blink is the only ongoing
   animation and it exists only during the terminal phase.
