narration

The baseline dev perplexity is 470.9. The corpus appears to be a genuinely noisy crawl, while the dev target has four sharply identifiable quarters: WikiText-style encyclopedia, polished web articles, news, and Stack Overflow-style Q&A. I’m using those disclosed distributions only as a density/style reference, with explicit equal token quotas so one easy-to-detect domain cannot crowd out the others.
