/* --------------------------------------------------------------------------
   EFFECT 2: CONSISTENT DROP SHADOWS & ROUNDED CORNERS
   PURPOSE:
   Harmonizes retro 8-bit chunky block shadows with modern subtle corner radii.
   - Border radius (4px - 8px) softens harsh edges for premium feel.
   - Hard drop shadow (4px - 6px) delivers authentic 90s console depth.
   - Neon glow ambient shadow (in dark mode) delivers cyberpunk arcade energy.
