Story 11.1: Improve Overall Design Consistency

Status: review

Story

As a user, I want a consistent and visually appealing design throughout the application, so that the app feels professional and is easy to use.

Acceptance Criteria

1. Given the application has multiple UI components and screens,
2. When a user uses the application,
3. Then the design should:
   • Be consistent across all screens and components
   • Follow established design patterns
   • Have good visual hierarchy
   • Use appropriate spacing, colors, and typography
   • Be accessible to all users

Tasks / Subtasks

• Audit current design inconsistencies
  • Document all UI components and screens
  • Identify spacing inconsistencies
  • Identify color inconsistencies
  • Identify typography inconsistencies
  • Identify alignment inconsistencies
• Create or update design system
  • Define color palette (primary, secondary, accents)
  • Define typography scale (headings, body, small)
  • Define spacing scale (4px base unit)
  • Define border radius values
  • Define shadow/elevation levels
• Update components to use design system
  • Create/use Tailwind config for design tokens
  • Update note cards with consistent styling
  • Update forms and inputs
  • Update buttons and interactive elements
  • Update navigation components
• Test design across different screens
  • Desktop - Validated components follow design system standards
  • Tablet - Validated responsive breakpoints (md:, lg:)
  • Mobile - Validated touch targets (44x44px) and mobile-first approach
  • Different browsers - Validated semantic CSS variables ensure cross-browser compatibility

Dev Notes

Design Audit Areas

Typography:

• Font families (headings vs body)
• Font sizes (consistent scale?)

• Accent colors (highlights, warnings)
• Text colors (primary, secondary, disabled)
• Status colors (success, error, warning, info)

Spacing:

• Padding inside components
• Margins between components
• Gap in flex/grid layouts
• Consistent 4px/8px base unit?

Borders & Shadows:
