AI writing reads more naturally, with a full pass on request

Content guidance for the AI now carries a writing-voice baseline: no em or en dashes, no promotional filler, no forced rule-of-three, no generic upbeat conclusions, plain verbs in place of "serves as" and "stands as". New lessons pick that up without anyone asking for it.

For lessons already in the library, a humanizer pass is available in the Saved Prompts picker, or by asking the agent to make the content sound less AI-written. It rewrites the tile prose across the lesson while preserving every fact and inventing no new detail.
