# Themes

Theme files override role tokens (`text.default`, `surface.*`, `border.*`)
without touching the underlying palette. To add a theme, copy `light/theme.json`
and supply your own values for each role token.

| Theme | File | Use |
|-------|------|-----|
| Light | `light/theme.json` | Default product theme. |
| Dark  | `dark/theme.json`  | Dimmed surfaces, reduced shadow weight. |
| High Contrast | `high-contrast/theme.json` | Accessibility: 7:1+ contrast. |
