/* ========================================
   CAROUSEL MODE - HORIZONTAL LAYOUT
   ========================================

   HOW TO EDIT LAYOUT:

   Footer distance from bottom:
     body.carousel-mode .footer { bottom: 0; }  <- change to "bottom: 20px" to raise

   Footer height:
     body.carousel-mode .footer .stack { height: 40px; }  <- change to "50px"

   Nav height:
     body.carousel-mode .nav-container .stack { height: 50px; }  <- change to "40px"

   Gap between nav and footer (viewport height):
     .carousel-viewport { height: calc(100% - 90px); }
     If nav is 50px and footer is 40px: 100% - 90px = 10px gap (already correct)
     If you change heights, adjust this formula!

   Nav transparency:
     body.carousel-mode .nav-container .stack-over { background: rgba(10, 14, 23, 0.85); }
     Change 0.85 to 0.5 for more transparent, 1.0 for solid

   Footer transparency:
     body.carousel-mode .footer .stack-over { background: rgba(10, 14, 23, 0.85); }
     Same adjustments as nav
