## Priority 1: Color System (30 minutes)

### Create Design Tokens File

**File: `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;
}
```

Import in `App.css`:
```css
@import "tailwindcss";
@import "./styles/design-tokens.css";
```

### Find & Replace Color Classes

**Throughout all components:**

```tsx
// Primary action buttons
bg-blue-600 → bg-primary
bg-blue-700 → bg-primary-dark
hover:bg-blue-700 → hover:bg-primary-light

// Text colors
text-blue-900 → text-primary-dark
text-blue-800 → text-primary
text-gray-600 → text-neutral-600
text-gray-900 → text-neutral-900

// Backgrounds
bg-gray-50 → bg-neutral-50
bg-gray-100 → bg-neutral-100

// Borders
border-gray-300 → border-neutral-300
```

---

## Priority 2: Button States (20 minutes)

### Standard Button Classes

**Replace all button classes with these variants:**

```tsx
// PRIMARY BUTTON (Connect, Upload, Start Sewing)
className="
  px-6 py-3
  bg-primary text-white
  rounded-lg font-semibold text-sm
  shadow-sm
  hover:bg-primary-light hover:shadow-md
  active:bg-primary-dark active:scale-[0.98]
  focus:outline-none focus:ring-2 focus:ring-primary focus:ring-offset-2
  disabled:bg-neutral-300 disabled:text-neutral-500 disabled:cursor-not-allowed
  transition-all duration-150
  cursor-pointer
"

// SECONDARY BUTTON (Mask Trace)
className="
  px-6 py-3
  bg-white text-neutral-700 border border-neutral-300
  rounded-lg font-semibold text-sm
  shadow-sm
  hover:bg-neutral-50 hover:border-neutral-400
  active:bg-neutral-100 active:scale-[0.98]
  focus:outline-none focus:ring-2 focus:ring-neutral-400 focus:ring-offset-2
  disabled:bg-neutral-50 disabled:text-neutral-400 disabled:cursor-not-allowed
  transition-all duration-150
  cursor-pointer
"

// DANGER BUTTON (Delete, Disconnect)
className="
  px-6 py-3
  bg-danger text-white
  rounded-lg font-semibold text-sm
  shadow-sm
  hover:bg-red-700 hover:shadow-md
  active:bg-red-800 active:scale-[0.98]
  focus:outline-none focus:ring-2 focus:ring-danger focus:ring-offset-2
  disabled:bg-neutral-300 disabled:text-neutral-500 disabled:cursor-not-allowed
  transition-all duration-150
  cursor-pointer
"

// ICON BUTTON (Zoom controls)
className="
  w-10 h-10
  flex items-center justify-center
  bg-white border border-neutral-300
  rounded-lg
  text-neutral-700
  hover:bg-primary hover:text-white hover:border-primary
  active:bg-primary-dark active:scale-95
  focus:outline-none focus:ring-2 focus:ring-primary focus:ring-offset-2
  transition-all duration-150
  cursor-pointer
"
```

**KEY CHANGES:**
- Remove `disabled:grayscale-[0.3]` everywhere
- Add `active:scale-[0.98]` for press feedback
- Add `focus:ring-2` for accessibility
- Use semantic color tokens

## Priority 3: Typography Scale (15 minutes)

### Standard Text Classes

**Apply throughout components:**

```tsx
// Headings
h1: "text-2xl font-bold text-neutral-900"           // Main title
h2: "text-xl font-semibold text-neutral-900"        // Section titles
h3: "text-base font-semibold text-neutral-900"      // Subsections
h4: "text-sm font-semibold text-neutral-700"        // Small headings

// Body text
"text-base text-neutral-900"      // Large body
"text-sm text-neutral-700"        // Regular body
"text-xs text-neutral-600"        // Small text
"text-[11px] text-neutral-500"    // Caption (minimal use)
```

### Quick Fixes

**WorkflowStepper.tsx:**
```tsx
// Line 102: Make step labels larger
<div className="text-sm font-semibold"> {/* was text-xs */}
```

**ProgressMonitor.tsx:**
```tsx
// Line 169: Larger thread labels
<span className="text-sm flex-1 font-semibold"> {/* was unlabeled size */}

// Line 179: More readable stitch counts
<span className="text-sm text-neutral-600 font-medium"> {/* was text-xs */}
```

**PatternCanvas.tsx:**
```tsx
// Line 278: Clearer thread legend text
<span className="text-sm text-neutral-900">Thread {index + 1}</span> {/* was text-xs */}
```

---

## Priority 4: Spacing Consistency (15 minutes)

### Standard Card Padding

**Apply to all card components:**

```tsx
// Standard card
<div className="bg-white p-6 rounded-lg shadow-md border border-neutral-100">

// Compact card (ProgressMonitor)
<div className="bg-white p-5 rounded-lg shadow-md border border-neutral-100">
```

### Standard Section Spacing

```tsx
// Between major sections
<div className="flex flex-col gap-6">

// Within sections
<div className="space-y-4">

// Within subsections
<div className="space-y-3">

// Tight grouping
<div className="space-y-2">
```

### Quick Fixes

**App.tsx:**
```tsx
// Line 126: Increase main grid gap
<div className="grid grid-cols-1 lg:grid-cols-[400px_1fr] gap-8"> {/* was gap-6 */}

// Line 128: Standard spacing in left column
<div className="flex flex-col gap-6">
```

**ProgressMonitor.tsx:**
```tsx
// Line 116: Better grid gap
<div className="grid grid-cols-1 md:grid-cols-2 gap-6"> {/* was gap-4 */}

// Line 143: Better color block spacing
<div className="flex flex-col gap-3"> {/* was gap-2 */}
```

---

## Priority 5: Visual Hierarchy (20 minutes)

### Section Headers

**Replace all section headers:**

```tsx
// OLD
<h2 className="text-xl font-semibold mb-4 pb-2 border-b-2 border-gray-300">

// NEW
<div className="mb-5 pb-3 border-b border-neutral-200">
  <h2 className="text-xl font-bold text-neutral-900">Pattern Preview</h2>
</div>
```

### Color Block Enhancement

**ProgressMonitor.tsx - Lines 157-191:**

```tsx
<div className={`
  p-3 rounded-lg border-2 transition-all duration-200
  ${isCompleted ? 'border-success bg-success-bg/50' : ''}
  ${isCurrent ? 'border-primary bg-primary/5 shadow-lg shadow-primary/10 ring-2 ring-primary/20' : ''}
  ${!isCompleted && !isCurrent ? 'border-neutral-200 bg-neutral-50 opacity-70' : ''}
`}>
  <div className="flex items-center gap-3">
    <div
      className="w-6 h-6 rounded-md border-2 border-white shadow-md ring-1 ring-neutral-300 flex-shrink-0"
      style={{ backgroundColor: block.threadHex }}
    />
    <span className="font-semibold text-sm flex-1">
      Thread {block.colorIndex + 1}
    </span>
    {/* Status icons */}
    {isCompleted && <CheckCircleIcon className="w-5 h-5 text-success" />}
    {isCurrent && <ArrowRightIcon className="w-5 h-5 text-primary" />}
    {!isCompleted && !isCurrent && <CircleStackIcon className="w-5 h-5 text-neutral-400" />}
    <span className="text-sm text-neutral-600 font-medium">
      {block.stitchCount.toLocaleString()}
    </span>
  </div>
  {/* Progress bar */}
  {isCurrent && (
    <div className="mt-2.5 h-1.5 bg-neutral-200 rounded-full overflow-hidden">
      <div
        className="h-full bg-primary transition-all duration-300"
        style={{ width: `${blockProgress}%` }}
      />
    </div>
  )}
</div>
```

## Priority 6: Accessibility Quick Wins (15 minutes)

### Add ARIA Labels to Icon Buttons

**PatternCanvas.tsx - Zoom controls:**

```tsx
<button
  onClick={handleZoomIn}
  aria-label="Zoom in on pattern preview"
  title="Zoom In"
  className="..."
>
  <PlusIcon className="w-5 h-5" />
</button>

<button
  onClick={handleZoomOut}
  aria-label="Zoom out from pattern preview"
  title="Zoom Out"
  className="..."
>
  <MinusIcon className="w-5 h-5" />
</button>

<button
  onClick={handleZoomReset}
  aria-label="Reset zoom to fit pattern"
  title="Reset Zoom"
  className="..."
>
  <ArrowPathIcon className="w-5 h-5" />
</button>
```

### Increase Touch Targets

**All icon buttons:**

```tsx
// Change from w-8 h-8 to w-10 h-10
<button className="w-10 h-10 ..."> {/* was w-8 h-8 */}
```

### Add Progress Bar ARIA

**ProgressMonitor.tsx - Line 207:**

```tsx
<div
  className="h-full bg-gradient-to-r from-primary to-primary-light transition-all duration-300"
  style={{ width: `${progressPercent}%` }}
  role="progressbar"
  aria-valuenow={progressPercent}
  aria-valuemin={0}
  aria-valuemax={100}
  aria-label="Sewing progress"
/>
```

## Priority 7: Polish Details (20 minutes)

### Better Progress Bar Styling

**Both upload and sewing progress bars:**

```tsx
<div className="h-2.5 bg-neutral-200 rounded-full overflow-hidden shadow-inner">
  <div
    className="h-full bg-gradient-to-r from-primary to-primary-light transition-all duration-300 ease-out relative overflow-hidden"
    style={{ width: `${progress}%` }}
  >
    {/* Shimmer effect */}
    <div className="absolute inset-0 bg-gradient-to-r from-transparent via-white/30 to-transparent animate-[shimmer_2s_infinite]" />
  </div>
</div>
```

### Enhanced Status Badges

**MachineConnection.tsx - Line 116:**

```tsx
<span className={`
  inline-flex items-center gap-2
  px-3.5 py-2
  rounded-lg
  font-semibold text-sm
  border border-current/20
  ${statusBadgeColors[stateVisual.color]}
`}>
  <span className="text-base leading-none">{stateVisual.icon}</span>
  <span>{machineStatusName}</span>
</span>
```

### Unified Canvas Overlays

**PatternCanvas.tsx - All overlays:**

```tsx
// Use consistent overlay styling
className="absolute ... bg-white/98 backdrop-blur-sm p-3 rounded-xl shadow-lg border border-neutral-200 z-10"
```
