## โ
What Was Implemented
### 1. Typography Hierarchy (FIXED)
**Before:**
```
Price: 48-60px (TOO BIG)
Title: 24-32px
```
**After (per UI/UX Guide):**
```
Title: 28-32px (PRIMARY)
Price: 24px (SECONDARY)
```
**Rationale:** We're not a marketplace (like Tokopedia). Title should be primary hierarchy.

## ๐ง Technical Implementation
### Key Components:
```tsx
// State management
const [selectedImage, setSelectedImage] = useState();
const [selectedVariation, setSelectedVariation] = useState(null);
const [selectedAttributes, setSelectedAttributes] = useState>({});
const [quantity, setQuantity] = useState(1);
const [activeTab, setActiveTab] = useState<'description' | 'additional' | 'reviews' | ''>('description');
// Image navigation
const thumbnailsRef = useRef(null);
const scrollThumbnails = (direction: 'left' | 'right') => { ... };
// Variation handling
const handleAttributeChange = (attributeName: string, value: string) => { ... };
// Auto-switch variation image
useEffect(() => {
if (selectedVariation && selectedVariation.image) {
setSelectedImage(selectedVariation.image);
}
}, [selectedVariation]);
```
### CSS Utilities:
```css
/* Hide scrollbar */
.scrollbar-hide::-webkit-scrollbar { display: none; }
.scrollbar-hide { -ms-overflow-style: none; scrollbar-width: none; }
/* Responsive visibility */
.hidden.md\\:block { display: none; }
@media (min-width: 768px) { .hidden.md\\:block { display: block; } }
/* Image override */
.\\!h-full { height: 100% !important; }
```

## ๐ฏ Key Decisions Made
### 1. Dots vs Thumbnails on Mobile
- **Decision:** Dots only (no thumbnails)
- **Rationale:** Convention (Amazon, Tokopedia, Shopify)
- **Evidence:** User screenshot of Amazon confirmed this
### 2. Pills vs Dropdowns
- **Decision:** Pills/buttons
- **Rationale:** Convention + Research align
- **Evidence:** Nielsen Norman Group guidelines
### 3. Title vs Price Hierarchy
- **Decision:** Title > Price
- **Rationale:** Context (we're not a marketplace)
- **Evidence:** Shopify (our closer analog) does this
### 4. Tabs vs Accordions
- **Decision:** Vertical accordions
- **Rationale:** Research (27% overlook tabs)
- **Evidence:** Baymard Institute study
### 5. Description Auto-Expand
- **Decision:** Auto-expanded on load
- **Rationale:** Don't hide primary content
- **Evidence:** Shopify does this
