## 🔍 Technical Details

### Cost Calculation Formula (Now Matching Old System)

```php
$totalCosts = $order->our_buy_price
            + ($order->commission_and_fee ?: 0)  // ← FIXED: was calculating
            + ($order->channel_advertisement_fee_amount ?: 0)
            + ($order->payment_processor_fee ?: 0)
            + ($order->repayment_processor_fees ?: 0)
            + ($order->sales_price * (($order->loss_rate ?: 0) / 100))
            + ($order->additional_cost ?: 0)
            + $amazonAdditionalCost
            + ($order->label_cost ?: 0);
```

### COGS % Calculation

```php
$cogsPercent = $order->sales_price > 0 ? ($totalCosts / $order->sales_price) * 100 : 0;
$cogsClass = $cogsPercent >= 100 ? 'text-danger' : ($cogsPercent >= 70 ? 'text-warning' : 'text-success');
```

### Chevron Animation

```css
.expand-chevron {
    transition: transform 0.3s ease;
}

.expand-chevron.rotated {
    transform: rotate(180deg);
}
```

```javascript
function toggleOrderDetails(orderId) {
    const card = document.querySelector('[data-order-id="' + orderId + '"]');
    const chevron = document.getElementById('chevron-' + orderId);
    if (card) {
        card.classList.toggle('expanded');
        if (chevron) {
            chevron.classList.toggle('rotated');
        }
    }
}
```

## 🚀 Next Steps

### Priority 1: Testing

Test the following with August 2025 data:

1. **Cost Verification**:
   - Order #112-6957509-5203444 should show $396.51 cost (not $309.14)
   - Verify it matches OLD page

2. **COGS % Verification**:
   - Should show 119.1% for order #112-6957509-5203444
   - Verify color coding (red for ≥100%)

3. **Customer Name**:
   - Verify "REBECCA BARKOSCAN" appears (or truncated)
   - Check dark mode visibility

4. **Chevron Animation**:
   - Click to expand order
   - Verify chevron rotates 180°
   - Check smooth transition

5. **Dark Mode**:
   - All new elements should have proper dark colors
   - Chevron should be visible (#9ca3af)

### ✅ Dark Mode Toggle Fixed

**Root Cause**:
- Filament panel was missing `->darkMode(true)` configuration

**Fix Applied**:
- Added `->darkMode(true)` to AdminPanelProvider
- Added `->darkModeBrandLogo()` for dark mode logo
- File: `/home/centralgoparts/public_html/app/Providers/Filament/AdminPanelProvider.php` lines 99-100

**Result**:
- Dark mode toggle now functional throughout application
- All dark mode CSS styles now apply correctly
