   Reusable glass morphism card with 3D tilt effects

   Modifiers:
   --interactive    : Enables 3D tilt on hover/click
   --static         : Display only, no interactions
   --nested         : For cards inside other glass cards (inherits parent tilt)

   Size modifiers:
   --poster         : 3:4 aspect ratio (default original)
   --square         : 1:1 aspect ratio
   --banner         : 4:1 aspect ratio
   --wide           : 16:9 aspect ratio
   --portrait       : 2:3 aspect ratio
   --landscape      : 4:3 aspect ratio
   --auto           : Natural content size

   Optional elements:
   __glow           : Color bleed effect behind card. Use with wrapper:
                      <div class="glass-card-wrapper">
                          <div class="glass-card__glow" style="background-image: url('...')"></div>
                          <div class="glass-card ...">...</div>
                      </div>

   Data attributes for --interactive cards:
   data-tilt-max        : Maximum tilt angle in degrees (default: 8)
   data-tilt-perspective: Perspective distance in px (default: 1000)
   data-parallax-amount : Image parallax movement in px (default: 5)
   data-lift-y          : Vertical lift on hover in px (default: 12)
   data-lift-z          : Z-axis lift on hover in px (default: 20)
