EdgeKit Design System Upgrade

Overview

Successfully upgraded the EdgeKit browser extension with a comprehensive design system based on Lovable.dev’s modern aesthetic.

Key Improvements

1. Design Tokens & Variables

• Color System: Implemented semantic color tokens with dark mode support
  • Primary colors: blue, emerald, amber, red with light/dim variants
  • Surface hierarchy: bg → surface → surface-2 → surface-3
  • Text hierarchy: text → text-dim → text-muted
  • Border colors with subtle transparency
• Typography:
  • Font weights: light (300) → regular (400) → medium (500) → semibold (600) → bold (700)
  • Font families: system sans-serif and monospace stacks
  • Consistent font sizes across components

• Spacing Scale: Consistent 4px-based scale (xs: 4px → 2xl: 32px)

• Border Radius: Standardized values (sm: 4px, md: 6px, lg: 8px, xl: 12px)

• Transitions: Smooth, consistent animations (100ms-300ms)

2. Component Enhancements

Headers & Navigation

• Modern gradient headers with improved typography
• Tab navigation with active state indicators
• Breadcrumb navigation with hover states

Buttons

• Three variants: primary, secondary, outline
• Three sizes: small, medium, large
• Consistent hover/active/disabled states
• Icon button support

Cards & Panels

• Layered surface system for depth
• Subtle borders and shadows
• Hover states for interactive cards

Status Indicators

• Color-coded HTTP status badges (2xx→5xx)
• Bordered badges for better visibility
• Monospace font for consistency

Waterfall Timeline (NEW)

• Visual request timeline with gradient bars
• Color-coded by HTTP method
• Performance metrics footer
• Responsive grid layout

Form Controls

• Styled inputs, selects, and textareas
• Focus states with ring indicators
• Disabled states
• Error states

3. Utility Classes

• Flexbox utilities (justify, align, gap)
• Grid utilities
• Spacing utilities (margin, padding)
• Text utilities (truncate, wrap)
• Display utilities

4. Dark Mode

• Full dark mode support via CSS variables
• Consistent contrast ratios
• Accessible color choices

Files Modified

• extension/shared/styles.css - Complete design system implementation

Design Principles Applied

1. Consistency: Unified spacing, colors, and typography
2. Hierarchy: Clear visual hierarchy through size, weight, and color
3. Accessibility: Sufficient contrast, focus indicators, readable fonts
4. Performance: CSS-only animations, minimal reflows
5. Maintainability: Token-based system, well-organized code

Next Steps

The design system is now ready for:

• Component integration in React/Vue components
• Additional component variants as needed
• Further customization per team preferences
