# Component Implementation Checklist

Step-by-step guide to implementing UI improvements in each component.

---

## Setup (Do First)

### 1. Create Design Tokens

**File: `C:\Users\micro\Documents\dev\respira-web\src\styles\design-tokens.css`**

```css
@theme {
  /* Primary - Blue */
  --color-primary: #2563eb;
  --color-primary-light: #3b82f6;
  --color-primary-dark: #1d4ed8;

  /* Secondary - Slate */
  --color-secondary: #64748b;
  --color-secondary-light: #94a3b8;

  /* Success - Green */
  --color-success: #16a34a;
  --color-success-bg: #dcfce7;

  /* Warning - Amber */
  --color-warning: #d97706;
  --color-warning-bg: #fef3c7;

  /* Danger - Red */
  --color-danger: #dc2626;
  --color-danger-bg: #fee2e2;

  /* Info - Cyan */
  --color-info: #0891b2;
  --color-info-bg: #cffafe;

  /* Neutral */
  --color-neutral-50: #f9fafb;
  --color-neutral-100: #f3f4f6;
  --color-neutral-200: #e5e7eb;
  --color-neutral-300: #d1d5db;
  --color-neutral-600: #4b5563;
  --color-neutral-900: #111827;
}
```

- [ ] Create file
- [ ] Add all color tokens

### 2. Update App.css

**File: `C:\Users\micro\Documents\dev\respira-web\src\App.css`**

```css
@import "tailwindcss";
@import "./styles/design-tokens.css";

/* Custom animations for shimmer effect */
@keyframes shimmer {
  0% {
    transform: translateX(-100%);
  }
  100% {
    transform: translateX(100%);
  }
}
```

- [ ] Import design tokens
- [ ] Verify shimmer animation exists

    <InformationCircleIcon className="w-8 h-8 text-blue-600 flex-shrink-0 mt-1" />

// AFTER
<div className="bg-info-bg border-l-4 border-info p-6 rounded-lg shadow-md">

**Apply similar changes to all state messages (lines 92-299)**

- [ ] Increase icon size (w-10 h-10)
- [ ] Use semantic colors (info, danger, warning, success)
- [ ] Ensure consistent styling across all states
- [ ] Verify border colors match semantic tokens

## Testing Checklist

After completing all component updates, test:

### Visual Tests
- [ ] All buttons have consistent rounded-lg corners
- [ ] All buttons show hover state (color change, shadow)
- [ ] All buttons show active state (scale down)
- [ ] Disabled buttons are gray, not grayscale filtered
- [ ] Colors are consistent (no stray blue-600/700)
- [ ] Spacing looks balanced
- [ ] Section headers stand out clearly

### Interaction Tests
- [ ] Tab through interface - all interactive elements show focus ring
- [ ] Click buttons - feel responsive with scale feedback
- [ ] Hover buttons - smooth color transitions
- [ ] Touch on mobile - 44px touch targets work well
- [ ] Zoom controls - easy to tap, clear feedback

### Accessibility Tests
- [ ] Screen reader announces progress bars correctly
- [ ] Button ARIA labels are present and clear
- [ ] Color contrast meets WCAG AA (4.5:1 text, 3:1 UI)
- [ ] Focus states visible on all elements
- [ ] Status conveyed by more than color alone

### Responsive Tests
- [ ] Mobile: Single column layout works
- [ ] Tablet: Grid layout switches correctly
- [ ] Desktop: Full two-column layout
- [ ] WorkflowStepper readable on all sizes
- [ ] Color blocks scroll on mobile

### State Tests
- [ ] Not connected: NextStepGuide shows step 1
- [ ] Connected: Components appear correctly
- [ ] Pattern loaded: Preview displays
- [ ] Uploading: Progress bar animates with shimmer
- [ ] Sewing: Color blocks highlight correctly
- [ ] Complete: Success states show green

## Estimated Time per Component

| Component | Time | Complexity |
|-----------|------|------------|
| Setup (tokens) | 10 min | Low |
| App.tsx | 10 min | Low |
| WorkflowStepper | 15 min | Medium |
| MachineConnection | 20 min | Medium |
| FileUpload | 25 min | High |
| ProgressMonitor | 35 min | High |
| PatternCanvas | 20 min | Medium |
| NextStepGuide | 15 min | Low |
| **Total** | **~2.5 hours** | |

---

## Quick Win Order

If you have limited time, implement in this order for maximum impact:

1. **Setup + App.tsx** (20 min) - Foundation
2. **MachineConnection buttons** (10 min) - Most visible
3. **ProgressMonitor color blocks** (20 min) - High impact
4. **WorkflowStepper** (15 min) - Always visible when connected
5. **FileUpload pattern grid** (15 min) - Clear improvement
6. **PatternCanvas zoom controls** (10 min) - Frequently used
7. **All other buttons** (15 min) - Consistency
8. **Polish and test** (20 min) - Final touches

**1.5 hour version**: Do steps 1-4
**2 hour version**: Do steps 1-6
**Full version**: All steps

---

## Common Pitfalls to Avoid

1. **Don't mix old and new colors** - Replace all instances at once per component
2. **Don't forget ARIA labels** - Add to all icon buttons
3. **Don't skip focus states** - Critical for accessibility
4. **Don't use grayscale filter** - Use neutral-300 background instead
5. **Don't make text too small** - Minimum 12px (text-xs)
6. **Don't forget active states** - Add scale-[0.98] to buttons
7. **Don't skip testing** - Test all states before moving to next component

---

## Success Criteria

You'll know the update is successful when:

- [ ] No blue-600/700 classes remain (except as fallbacks)
- [ ] No grayscale filters on disabled buttons
- [ ] All buttons have focus:ring-2
- [ ] All progress bars have shimmer effect
- [ ] Color blocks visually distinct (completed/current/upcoming)
- [ ] Touch targets minimum 44px
- [ ] Consistent rounded-lg on all buttons
- [ ] Semantic color tokens used throughout
- [ ] ARIA labels on all icon buttons
- [ ] Interface feels more polished and professional
