shopper

Read live marketplace listings the way an agent can: first-party API, no scraping. ebay.com HTML is 403 bot-blocked from this box (even headless chromium — IP-level), so the Browse API is the only sanctioned view.

• eBay — ebay.md: item-detail recipe (versioned IDs), search, credentials, the 11001 gotcha.
• Working code lives in ~/repos/arc-shopper/sources/ — ebay.mjs (search), ebay-item.mjs (item detail). Reuse it; don't re-derive it.
