🎨 Design Tokens (CSS Variables)

All repoUI styles are driven by CSS variables, making them easy to customize:

:root {
  --repo-color-primary: #3b82f6;      /* Primary color */
  --repo-color-danger: #ef4444;       /* Danger color */
  --repo-color-success: #10b981;      /* Success color */
  --repo-color-warning: #f59e0b;      /* Warning color */
  --repo-font-family: -apple-system, "Segoe UI", sans-serif;
  --repo-radius-md: 6px;              /* Radius */
  --repo-spacing-4: 16px;             /* Spacing */
  /* ...more variables in repoUI.css */
}
