From a brand palette (or a single color via /palette), generate:
Surface tokens: surface, surface-elevated, surface-sunken, surface-overlay Text tokens: text, text-secondary, text-muted, text-inverse Border tokens: border, border-strong, border-subtle Accent tokens: accent, accent-hover, accent-pressed, accent-subtle Feedback tokens: danger, danger-subtle, success, success-subtle, warning, warning-subtle, info, info-subtle Interactive tokens: focus-ring, disabled, disabled-text
All tokens must have dark mode variants. Output as CSS custom properties inside :root and @media (prefers-color-scheme: dark).
