Design System Integration

Typography (Google Fonts)

• Primary Font: Inter (headings, UI elements)
• Secondary Font: Source Sans Pro (body text)
• Accent Font: Roboto Mono (code, technical content)

Design Token Usage

// Import design system tokens
@use 'ui-design-system/src/styles/tokens' as tokens;

.hero-section {
  padding: tokens.$spacing-section-large tokens.$spacing-container;
  background: tokens.$color-surface-primary;
  
  .hero-title {
    font-family: tokens.$font-family-heading;
    font-size: tokens.$font-size-display-large;
    color: tokens.$color-text-primary;
    margin-bottom: tokens.$spacing-content-medium;
  }
}

Spacing Hierarchy

• Section Padding: $spacing-section-large (96px), $spacing-section-medium (64px)
• Content Spacing: $spacing-content-large (48px), $spacing-content-medium (32px)
• Element Spacing: $spacing-element-large (24px), $spacing-element-medium (16px)
