Design system
A design system is the shared set of colours, type, spacing and components a site is built from, written down so anyone can reuse it.
Why it matters
It keeps new pages consistent without a designer on every change, and it makes the site faster because the same small set of styles is loaded once.
In practice
- Start with tokens: colour, type scale, spacing, radius.
- Add only the components the site actually uses.
- Document each one with a live example.
