Minimal, per Dynaword guidelines (heavy filtering left to downstream use):
- drop documents < 200 chars: **0**
- drop non-Polish (diacritic ratio): **15**
- exact cross-source dedup (sha1): **0**
- OCR alpha-ratio < 0.70 (OCR sources only): **0**
- read 632,020 → kept 632,005

Token counts are a fast tiktoken (cl100k) proxy (~1% off Llama-3); the canonical
Llama-3 count is computed at release.
