# Design Audit Findings - Story 11.1

**Generated:** 2026-01-17
**Project:** Keep

## Executive Summary

This document outlines design inconsistencies found during the audit of the Keep application. The goal is to establish a consistent design system that improves visual hierarchy, usability, and maintainability.

---

## 1. Spacing Inconsistencies

### Current State
- **Padding inconsistencies across components:**
  - NoteCard: `p-4` (16px)
  - Card: `py-6 px-6` (24px/24px)
  - Input: `px-3 py-1` (12px/4px)
  - Badge: `px-2 py-0.5` (8px/2px)
  - Button (sm): `px-3` (12px)
  - Button (default): `px-4` (16px)
  - Header search: `px-4 py-3` (16px/12px)

- **Margin/gap inconsistencies:**
  - NoteCard: `mb-2`, `mt-3`, `gap-1`
  - FavoritesSection: `mb-8`, `mb-4`, `gap-2`, `gap-4`
  - Header: `space-x-3` (12px horizontal gap)

### Issues Identified
1. No consistent base unit usage (should be 4px)
2. Different padding values for similar components
3. Inconsistent gap/margin values between sections

### Recommended Standardization
```css
/* Tailwind spacing scale (4px base unit) */
p-1: 0.25rem (4px)
p-2: 0.5rem (8px)
p-3: 0.75rem (12px)
p-4: 1rem (16px)
p-6: 1.5rem (24px)

gap-1: 0.25rem (4px)
gap-2: 0.5rem (8px)
gap-3: 0.75rem (12px)
gap-4: 1rem (16px)
```

**Standard Components:**
- Cards: `p-4` (16px) for padding
- Buttons: `px-4 py-2` (16px/8px) default
- Inputs: `px-3 py-2` (12px/8px)
- Badges: `px-2 py-0.5` (8px/2px)
- Form sections: `gap-4` (16px)

---

## 2. Border Radius Inconsistencies

### Current State
- **Different border radius values:**
  - NoteCard: `rounded-lg` (0.5rem/8px)
  - Card: `rounded-xl` (0.75rem/12px)
  - Button: `rounded-md` (0.375rem/6px)
  - Input: `rounded-md` (0.375rem/6px)
  - Badge: `rounded-full` (9999px)
  - Header search: `rounded-2xl` (1rem/16px)
  - FavoritesSection header: `rounded-lg` (0.5rem/8px)
  - Grid view button: `rounded-xl` (0.75rem/12px)
  - Theme toggle: `rounded-xl` (0.75rem/12px)

### Issues Identified
1. Inconsistent corner rounding across UI elements
2. Multiple radius values without clear purpose

### Recommended Standardization
```css
/* Standard border radius values */
rounded: 0.25rem (4px)     - Small elements (icons, small badges)
rounded-md: 0.375rem (6px)  - Inputs, small buttons
rounded-lg: 0.5rem (8px)    - Cards, buttons, badges (default)
rounded-xl: 0.75rem (12px)   - Large containers, modals
rounded-2xl: 1rem (16px)    - Hero elements, search bars
rounded-full: 9999px        - Circular elements (avatars, pill badges)
```

**Component Standards:**
- Cards/NoteCards: `rounded-lg` (8px)
- Buttons: `rounded-md` (6px)
- Inputs: `rounded-md` (6px)
- Badges (text): `rounded-full` (pills)
- Search bars: `rounded-lg` (8px)
- Icons: `rounded-full` (circular)
- Modals/Dialogs: `rounded-xl` (12px)

## 3. Shadow/Elevation Inconsistencies

### Current State
- **NoteCard:** `shadow-sm hover:shadow-md`
- **Card:** `shadow-sm`
- **Header search:** `shadow-sm`
- **Header buttons:** `hover:shadow-sm`

### Issues Identified
1. Limited use of elevation hierarchy
2. No clear shadow scale for different UI depths

### Recommended Standardization
```css
/* Tailwind shadow scale */
shadow-sm: 0 1px 2px 0 rgb(0 0 0 / 0.05)
shadow: 0 1px 3px 0 rgb(0 0 0 / 0.1)
shadow-md: 0 4px 6px -1px rgb(0 0 0 / 0.1)
shadow-lg: 0 10px 15px -3px rgb(0 0 0 / 0.1)
```

**Component Standards:**
- Cards: `shadow-sm` (base), `hover:shadow-md` (interactive)
- Buttons: No shadow (flat), `hover:shadow-sm` (optional)
- Modals: `shadow-lg` (elevated)
- Dropdowns: `shadow-lg` (elevated)

---

## 4. Typography Inconsistencies

### Current State
- **Font sizes vary:**
  - NoteCard title: `text-base` (16px)
  - NoteCard content: `text-sm` (14px)
  - NoteCard badges: `text-xs`, `text-[10px]`
  - Button: `text-sm`
  - Input: `text-base` (mobile), `md:text-sm`
  - Badge: `text-xs`
  - FavoritesSection title: `text-xl` (20px)
  - FavoritesSection subtitle: `text-sm`
  - Header search: `text-sm`
  - Header nav items: `text-sm`

- **Font weights:**
  - NoteCard title: `font-medium`
  - Button: `font-medium`
  - Badge: `font-medium`
  - FavoritesSection title: `font-semibold`

### Issues Identified
1. No clear typography hierarchy
2. Inconsistent font weights across headings
3. Custom font sizes (`text-[10px]`) instead of standard scale

### Recommended Standardization
```css
/* Typography scale (Tailwind defaults) */
text-xs: 0.75rem (12px)   - Labels, small text, badges
text-sm: 0.875rem (14px)  - Body text, buttons, inputs
text-base: 1rem (16px)    - Card titles, emphasized text
text-lg: 1.125rem (18px)  - Section headers
text-xl: 1.25rem (20px)   - Page titles
text-2xl: 1.5rem (24px)  - Large headings

/* Font weights */
font-normal: 400  - Body text
font-medium: 500  - Emphasized text, button labels
font-semibold: 600  - Section titles
font-bold: 700  - Major headings
```

**Typography Hierarchy:**
- Page titles: `text-2xl font-bold` (24px)
- Section headers: `text-xl font-semibold` (20px)
- Card titles: `text-lg font-medium` (18px)
- Body text: `text-sm text-gray-700` (14px)
- Button labels: `text-sm font-medium` (14px)
- Labels/badges: `text-xs font-medium` (12px)
- Metadata: `text-xs text-gray-500` (12px)

## 5. Color Usage Inconsistencies

### Current State
- **Hardcoded color classes in components:**
  - NoteCard: `bg-blue-100`, `bg-purple-900/30`, `text-blue-600`, `text-purple-400`, `text-gray-900`, `text-gray-700`, `text-gray-500`
  - Header: `bg-background-light/90`, `text-slate-500`, `text-amber-500`, `text-indigo-600`
  - FavoritesSection: `text-gray-900`, `text-gray-500`

### Issues Identified
1. Colors not using CSS custom properties (variables)
2. Inconsistent color naming (gray vs slate vs zinc)
3. Mixed color semantics (functional vs semantic)

### Recommended Standardization
- Use CSS custom properties already defined in globals.css
- Apply semantic color naming through Tailwind utility classes
- Standardize color usage patterns:
  ```css
  /* Use existing CSS variables */
  --primary, --secondary, --accent, --destructive
  --foreground, --muted-foreground, --card-foreground
  --border, --input, --ring
  ```

## 6. Transition/Animation Inconsistencies

### Current State
- **Transition values:**
  - NoteCard: `transition-all duration-200`
  - FavoritesSection: `transition-colors`
  - Header buttons: `transition-all duration-200`

### Issues Identified
1. Inconsistent transition property usage
2. Varying durations without clear purpose

### Recommended Standardization
```css
/* Standard transitions */
transition-colors duration-200  - Color changes (hover states)
transition-all duration-200       - Multiple property changes
transition-opacity duration-150   - Fade in/out
transition-transform duration-200 - Movement/position
```

**Component Standards:**
- Buttons/hover states: `transition-colors duration-200`
- Cards: `transition-all duration-200`
- Modals/overlays: `transition-opacity duration-150`

---

## 7. Component-Specific Issues

### NoteCard Issues
- Hardcoded colors (`bg-blue-100`, etc.) not using theme variables
- Inconsistent padding (`p-4`) vs other cards (`py-6 px-6`)
- Badge with custom `text-[10px]` not following typography scale

### Button Issues
- Inconsistent padding between variants (sm vs default)
- Some buttons using hardcoded blue colors instead of theme colors

### Input Issues
- Inconsistent base font size (`text-base` vs `md:text-sm`)

### Header Issues
- Search bar uses `rounded-2xl` (16px) which is too round for search
- Inconsistent spacing (`px-6 lg:px-12`)
- Hardcoded colors (`bg-white dark:bg-slate-800/80`) not using theme variables

### Badge Issues
- `rounded-full` (pills) vs inconsistent usage elsewhere
- Good: Uses CSS variables for colors

---

## 8. Accessibility Concerns

### Current State
- **Touch targets:**
  - Some buttons: `h-8 w-8` (32px) - below 44px minimum
  - Header buttons: `p-2.5` (20px) - below 44px minimum

### Issues Identified
1. Touch targets below WCAG 2.1 AA minimum (44x44px)
2. Focus indicators inconsistent (some `focus-visible`, some not)

### Recommended Fixes
- Increase touch target size to minimum 44x44px on mobile
- Ensure all interactive elements have focus-visible states
- Use `min-h-[44px] min-w-[44px]` for mobile buttons

## 9. Component Priority Matrix

### High Priority (Core User Experience)
1. **NoteCard** - Primary UI component, seen frequently
2. **Button** - Used throughout app
3. **Input** - Form interactions
4. **Header** - Global navigation

### Medium Priority (Secondary UI)
1. **Card** - Container component
2. **Badge** - Status indicators
3. **Label/Badge components** - Filtering
4. **Modals/Dialogs** - User interactions

### Low Priority (Enhancements)
1. **Animations** - Motion design
2. **Loading states** - Skeleton screens
3. **Empty states** - Zero-state design
4. **Error states** - Error handling UI
