For simplicity, let's analyze the most commonly used ones. \n\n1) **Design Tokens and CSS Variables**: Vercel utilizes CSS custom properties (variables). They are often declared in a global :root{} selector for access across the entire document. Here is an example:\n\n```css\n:root {\n  --font-size-small: 14px;\n}\n\nbody {\n  font-size: var(--font-size-small);\n}\n```\nThis way, you can change all instances of a particular property (like the font size) in one place. It also helps with maintainability and scalability as changes to design tokens are less frequent than codebase changes.\n\n2) **Grid Layout**: Vercel's CSS uses a grid layout system for its main page layout. Here is an example of how they might structure their CSS:\n```css\nbody {\n  display: grid;\n  grid-template-columns: repeat(12, minmax(0, 1fr));\n}\n\n.container {\n  grid-column: span 12;\n}\n```\nIn this case, the body of the document is set to a grid layout with 12 columns of equal width that take up the full available space. Inside containers are set to span across one column (12 units). This allows for complex layouts with responsive breakpoints.\n\n3) **Color System**: Vercel uses color variables in their design system, here is an example:\n```css\n:root {\n  --color-primary: #067df7;\n}\n\na {\n  color: var(--color-primary);\n}\n```\nIn this case, the primary color variable is set to a specific hex code, and all anchor tags will have that color unless otherwise specified. This way they can easily change colors in one place if needed without having to update each individual tag's styling.\n\n4) **Component Patterns**: Vercel uses patterns like modals, tooltips, popovers etc., which are often defined globally using CSS classes and then applied elsewhere where required. Here is an example of a modal:\n```css\n.modal {\n  display: none;\n}\n\n.show-modal .modal {\n  display: block;\n}\n```\nIn this case, the `.modal` class would be hidden by default but become visible when any element with the class 'show-modal' is present.\n\n5) **Animation Design**: Vercel often uses CSS animations to create a smooth user experience. They are usually simple and short, like fading in/out or sliding panels. Here is an example of a fade-in animation:\n```css\n@keyframes fadeIn {\n  from { opacity: 0; }\n  to   { opacity: 1;
