/**
 * Integration tests for EbayAdapter against the eBay Sandbox.
 *
 * The Inventory/Offer APIs require a user-level OAuth token (Authorization Code
 * grant with sell.inventory scope) — app token alone is insufficient.
 *
 * Set EBAY_USER_TOKEN in .env.local to enable listing tests:
 *   EBAY_USER_TOKEN=v^1.1#i^1#I^3#...
 *
 * Taxonomy / auth tests run with just the app token.
 *
 * Run with: bin/test-integration tests/Integration/Infrastructure/Channel/Ebay/
