  /* Shadows in dark mode are often more subtle or can be emulated with light borders/glows.
     Keeping existing shadow structure but their visual impact will be reduced.
     For a more pronounced "elevation" feel, you might use a very subtle lighter inner or outer glow
     or slightly lighter background for elevated elements.
     Example: --shadow-md: 0 4px 12px rgba(0,0,0,0.3); (darker shadow)
     or using a semi-transparent white for a glow:
     --shadow-md: 0 0 15px rgba(200, 200, 255, 0.03);
     For now, we'll keep the original shadow definition but expect them to be less visible.
