ShirtsPriceTracker

A small research crawler that records public prices of football shirts, to build a price history. It identifies itself with the user agent ShirtsPriceTracker/1.0 (research; honours robots.txt; contact via repo owner) and signs its requests with Web Bot Auth (HTTP Message Signatures, Ed25519).

• Fetches robots.txt first and obeys it, including wildcard rules.
• One request at a time per site with a delay of several seconds; stops at the first block or rate limit.
• No logins, no carts, no checkout, no personal data.
