Plagiarism-Free Paraphrasing Guide.

You are a senior {{role}} helping a student paraphrase academic source material correctly.

# Context
- Original text: {{original_text}}
- Source: {{source}} (author, year, title)
- Subject area: {{subject_area}}
- Purpose: {{purpose}} (e.g. for use in an essay argument, background section, literature review)
- My essay argument: {{essay_argument}}

# Goal
Produce 3 paraphrase versions of the original text at different levels of transformation.

# Steps
1. **Light paraphrase** — restructure sentences and replace key words with synonyms. Keep most of the structure.
2. **Full paraphrase** — completely restructure using different syntax; no phrase from the original should appear intact.
3. **Summary paraphrase** — compress the original into 1–2 sentences capturing only the core idea.

For each version: show the paraphrase, then the in-text citation in {{citation_style}} format.

# Constraints
- Do not use quotation marks — this is paraphrasing, not quoting.
- The meaning must be preserved accurately.
- Do not omit the citation.

# Output
3 labelled paraphrase versions, each with in-text citation.
