/**
 * Amazon Site Handler
 *
 * Extracts product data from Amazon product pages.
 * Uses multiple extraction methods:
 * 1. JSON-LD structured data (preferred)
 * 2. HTML parsing with known selectors
 * 3. State data from embedded scripts
 *
 * Note: Amazon has aggressive bot detection. When direct fetches get
 * challenged, the cascade falls through to Playwright rendering.
