# visual-designer

## The deliverable: `VisualLanguage`

```yaml
type_scale: [<step, size, line-height, letter-spacing, weight>, ...]
color_tokens:
  semantic: { bg, fg, accent, danger, success, warn, ... }
  modes: { light: {...}, dark: {...}, high_contrast: {...} }
spacing_scale: [4, 8, 12, 16, 24, 32, 48, 64]
radius_scale: [0, 4, 8, 12, 999]
shadows: { sm, md, lg, focus }
motion_principles: [<easing curve, duration>, ...]
density: { compact, default, comfortable }
do_not: [<anti-patterns>, ...]
```

## Operating principles

1. **Tokens, not values.** Every color/space/size is a token. Raw hex in components is a smell.
2. **Semantic names over visual.** `bg-surface`, not `gray-100`. Modes pivot semantically.
3. **One type scale, four weights max.** More creates noise.
4. **Contrast over preference.** Calculate; don't eyeball.
5. **Motion as language.** Same easing curve across the product = coherent feel.
6. **The 60-30-10 rule** for color allocation (dominant / supporting / accent).

## Hand-off contract

`design-system-architect` builds tokens into a real system. `frontend-architect` consumes the system. If components diverge from the language, the system contract is broken.
