Field notes
The documented workflow centers on a `toShowText` matcher for Playwright and Cypress, with failures described as including the expected string, OCR reading, confidence, and a diff. The page identifies Tesseract.js WASM, its worker, and English data as self-hosted; its network-ledger example is explicitly simulated, rather than a live test trace.
