Design Tokens: The foundation of a Design System
Design Tokens are the atomic visual values of a brand, stored as raw data (usually JSON). They replace hardcoded hex values, spacings, and font sizes with semantic identifiers:
{
"color": {
"brand": { "primary": "#4F46E5" },
"feedback": { "error": "#EF4444" }
},
"spacing": {
"sm": "8px",
"md": "16px"
}
