## 📦 Deploy to cPanel

### Step 1: Clean Up cPanel
```bash
# SSH into cPanel
cd ~/CompareKit
rm -rf *
```

### Step 2: Upload & Extract
1. Upload `CompareKit-with-frontend-controls.zip` via cPanel File Manager
2. Extract it (right-click → Extract)

### Step 3: Install Dependencies

cd ~/CompareKit
npm install
```

**Note:** If `exiftool-vendored` or `unsplash-js` fail to install, that's OK!
- The code has try/catch blocks for graceful fallback

NODE_ENV=production
```

### Step 5: Restart App

## 🎨 How to Use New Features

### 1. Unsplash Toggle
**Location:** Below "Popular Comparisons" section

**Usage:**
- ✅ **Checked** (default): Fetches real photos from Unsplash API
- ❌ **Unchecked**: Uses only local background files from `/public/assets/backgrounds/`

**When to disable:**
- Want consistent local backgrounds
- Unsplash API quota exceeded
- Faster generation (no API calls)

---

### 2. Custom Unsplash Search Query
**Location:** Visible when Unsplash toggle is ON

**Usage:**
- Leave **empty** for automatic category matching
- Enter **custom query** for specific themes

**Examples:**
- `modern office workspace computer desk` (default)
- `sunset beach office`
- `minimalist workspace dark`
- `tech startup innovation`
- `coworking space collaboration`

**Tips:**
- More specific = better results
- Use 3-5 words max
- Avoid generic terms like "background"

---

### 3. Background Effects Intensity
**Location:** Dropdown below Unsplash controls

**Options:**

#### 🔴 Off (0)
- Clean minimal look
- **NO** bokeh particles
- **NO** lighting effects
- **NO** energy effects around VS
- **NO** texture overlays (grain, noise)
- Only logos + VS element + background photo
- **Best for:** Professional corporate images

#### 🟡 Low (0.33)
- Subtle atmospheric effects
- ~33 bokeh particles (reduced from 100)
- Reduced lighting (30% opacity)

#### 🟠 Medium (0.66)
- Balanced visual effects

- 100 bokeh particles
- Full lighting (100% opacity)
- Dramatic energy effects
- All texture overlays
- **Best for:** Eye-catching featured images

## 🧪 Testing Checklist

After deployment, test these scenarios:

### Test 1: Unsplash ON + High Effects
- [x] Check "Use Unsplash Backgrounds"
- [x] Leave query empty
- [x] Select "High - Full effects"
- [x] Generate image
- **Expected:** Unsplash photo + full bokeh/lighting effects

### Test 2: Unsplash OFF + No Effects
- [x] Uncheck "Use Unsplash Backgrounds"
- [x] Select "Off - Clean minimal look"
- [x] Generate image
- **Expected:** Local photo + no effects (clean look)

### Test 3: Custom Query + Low Effects
- [x] Check "Use Unsplash Backgrounds"
- [x] Enter "sunset office workspace"
- [x] Select "Low - Subtle effects"
- [x] Generate image
- **Expected:** Sunset-themed Unsplash photo + subtle effects

### Test 4: Fallback Behavior
- [x] Check "Use Unsplash Backgrounds"
- [x] Enter nonsense query like "zzzzzzzzz"
- [x] Generate image
- **Expected:** Falls back to local photo gracefully (no errors)

## 🐛 Troubleshooting

### Images are black locally
**Cause:** Node.js v23 compatibility issue with canvas library
**Solution:** This is LOCAL ONLY - images work fine on cPanel with Node v18/v20
**Action:** Deploy to cPanel, don't worry about local black images

### Unsplash not working
**Check console for:**
- `Unsplash disabled by user, using local photos only` → Toggle is OFF
- `Unsplash failed: [error], falling back to local` → API issue, using fallback
- `⚠️ Unsplash API key not configured` → Check `.env` file

**This is NOT an error!** The app automatically falls back to local photos.

### EXIF metadata failed
**Console shows:**
- `⚠️ EXIF metadata failed (not critical): [error]`
- `Returning image without EXIF metadata`

**This is NOT an error!** Images generate without EXIF metadata (not critical for display).

### Effects not changing
**Verify:**
- Dropdown value is changing in browser
- Check browser console for JavaScript errors
- Try hard refresh (Cmd+Shift+R or Ctrl+Shift+R)

---

## 📋 What to Expect on cPanel

### ✅ Images Will Have:
- Real Unsplash photos (or local fallback)
- NO connection lines (burst/particles around VS only)
- Horizontal layouts ONLY
- Customizable effects based on intensity setting
- Professional brand colors
- Delete All Images button working

### Optional Features (graceful fallback):
- **Unsplash:** Works if API key valid, falls back to local
- **EXIF:** Added if exiftool installs, skipped otherwise
- Both features are non-critical and won't break the app
