/* Simple cross-fade between the intro card and the site content. Hiding
   uses position:absolute + opacity, never display:none — switching an
   element to display:none and back resets every CSS animation inside it
   (the video card entrances, tab fades, etc.), which is what made the
   reveal feel like a stutter/freeze. Position swap avoids that entirely. */
