   Blue Penguin Digital — Design System v4
   theme-v4.css — The Component, Polish & Animation Layer
   
   This sits alongside Tailwind CSS. Tailwind handles utility layout;
   this file handles everything Tailwind alone cannot:
   - Design tokens as CSS custom properties
   - Multi-layered, tinted shadow system
   - Pseudo-element shadow animation (GPU-composited)
   - Component layer: buttons, forms, cards, accordions, nav, tables
   - Scroll reveals, counter animations, smooth scroll
   - content-visibility performance helpers
   - Accessibility: focus rings, reduced motion, skip-to-content
   
   Version: 4.0.0
