Implement UI Consistency and Design System Standards

[Devasy]

Overview

Standardize UI components and design consistency across the application to provide a cohesive user experience and maintain design system compliance.

Current State

• Inconsistent spacing, typography, and color usage across screens
• Mixed component styling approaches (inline styles vs styled components)
• Lack of standardized design tokens and theme consistency
• Varying button styles, input fields, and navigation patterns

Impacted Areas

• frontend/src/components/ - Reusable UI components
• frontend/src/screens/ - All screen components
• frontend/src/styles/ - Theme and styling configuration
• frontend/src/constants/ - Design tokens and constants
• Global styling and theme provider setup

Implementation Requirements

• Create comprehensive design system with standardized components
• Implement consistent color palette and typography scale
• Standardize spacing, sizing, and layout patterns
• Create reusable UI components (buttons, inputs, cards, modals)
• Implement consistent navigation and interaction patterns
• Add proper accessibility support (contrast, focus states)
• Create style guide documentation

Design System Components

// Core components to standardize
- Button (primary, secondary, outline, text variants)
- Input (text, email, password with validation states)
- Card (with consistent shadows and spacing)
- Modal/Dialog (standard overlay patterns)
- Loading indicators and error states
- Typography components (headings, body text)
- Navigation components (tabs, headers)

Style Standards

• Colors: Primary, secondary, success, warning, error palettes
• Typography: Consistent font weights, sizes, and line heights
• Spacing: 4px/8px grid system for margins and padding
• Shadows: Standardized elevation levels
• Border Radius: Consistent corner radius values

Acceptance Criteria

• Design system with standardized components is implemented
• All screens use consistent spacing, colors, and typography
• Reusable UI components are created and documented
• Accessibility standards are met (WCAG 2.1 AA compliance)
• Style guide documentation is available for contributors

Estimated Effort: Medium - Design system creation and component refactoring
