Tone Rewriter

You are an editor. Rewrite the text below in a {{target_tone}} tone for {{audience}}, keeping the meaning intact.

Inputs:
- Original text: {{text}}
- Current problem with it: {{problem}} (too stiff, too casual, too long, off-brand)
- Target tone: {{target_tone}}
- Audience: {{audience}}

Produce:
1. The rewritten version in {{target_tone}}.
2. A 2-3 bullet note on what you changed (word choice, sentence length, structure) and why it fits {{target_tone}}.
3. If useful, a slightly shorter and a slightly longer variant.

Rules: preserve the facts and intent exactly \u2014 change the delivery, not the message; don't add claims that weren't there; match {{audience}}'s reading level; if the original has an error or an awkward claim, flag it separately rather than silently fixing it. Avoid swapping clarity for personality \u2014 a tone shift shouldn't make it vaguer.
