## Changelog

### 🚀 0.1 — Initial release

- 🃏 Scrapes MySlabs.com graded trading-card listings (PSA/BGS/CGC/SGC/HGA/TAG) from schema.org JSON-LD -- title, price, currency, availability, condition, images, and shipping, with grading company and grade parsed from the title.
- 🔍 Four search surfaces (all/auction/bin/private-deals), a full-inventory sitemap crawl, and direct-URL mode.
- 🆕 `diffMode` incremental crawling: tracks a per-run seen-listing-ID baseline and stops early once listing-grid pages (newest-first) reach a previously-seen ID -- built for scheduled price-monitoring runs.
- 🛡️ Reliability-focused defaults (generous retries, conservative concurrency, per-request timeout) aimed at beating the leading competitor actor's ~19.5% FAILED/TIMED-OUT/ABORTED rate.
- 🚫 Seller username and cert number are left `null` rather than fabricated: confirmed live that both are absent from anonymous JSON-LD, the seller-name block renders "Log In to view" for anonymous requests, and the on-page cert field is an empty lookup form, not populated data.
