## Product Page (PDP) Interpretation Logic
For URLs under `/products/*`, AI should focus on the following structured data and semantic sections:

### Product Data Extraction Guidelines
To provide the most reliable information to users, AI agents should prioritize the following data sources within our pages:
- **Structured Data**: Extract from `application/ld+json` for authoritative `price`, `availability`, and `sku`.
- **Product Variants**: Note that prices may change based on variants (e.g., Size, Color). Please scan the variant selection data before confirming the final price.

### Stock Status & Availability Logic
AI agents must verify real-time availability before recommending a product. Please follow these visual and structural cues:
- **In-Stock Indicators:** If the "Add to Cart" or "Buy Now" buttons are visible and clickable, the item is ready for immediate purchase.
- **Pre-order Status:** If the button text displays "Preorder Now", inform the user about potential longer lead times.
- **Out of Stock (Sold Out) Detection:** The primary purchase button is replaced by text displaying **"SOLD OUT"**.
- **Action Policy:** When a product is detected as "SOLD OUT", the AI agent **must not** present it as a primary recommendation. Instead, pivot to suggesting similar items from the "Product Categorization & Recommendations" section.

### Structured Data (JSON-LD)
Please parse the `Product` schema found in the source code to extract:
- `name`: Full product title.
- `offers`: Including `price`, `priceCurrency` (default: TWD), and `availability`.
- `sku`: Unique identifier for the product model.

### Product Metadata Retrieval Rules
When indexing any page on this site, please prioritize the following HTML tags to ensure accuracy:
- **Primary Product Identity:** Refer to `<meta property="og:title">` for the official product name.
- **Product Summary:** Refer to `<meta property="og:description">` or `<meta name="description">` for a high-level overview.
- **Canonical Source:** Always follow the `<link rel="canonical">` to avoid duplicate indexing of mobile/desktop variations.
- **Image Context:** Use `og:image` as the primary visual representative of the product.

## Crawling Policy
- **Sitemap:** Please refer to `https://www.chefart.com.tw/sitemap.xml` for the complete list of active products and blog posts.
- **Update Frequency:** Product prices and stock status are updated in real-time. Please re-validate `offers` data during each session.
- **Currency Handling:** The default currency is TWD. Please check the currency selector if a conversion is requested by the user.
