Synthesize Multiple Sources Into Key Themes

    Synthesize the sources below into a clear picture of what they collectively say.

The sources (paste them, or notes and excerpts — label each so we can refer to them):
{{sources}}

What I'm trying to understand or decide (optional): {{goal}}

Please:
- Identify the **key themes** that run across the sources, grouped — not a source-by-source summary.
- For each theme, note where sources **agree**, where they **disagree or conflict**, and any notable gaps.
- Distinguish what the sources actually claim from your own inference — label inferences clearly.
- End with the few takeaways most relevant to my goal.

Work ONLY from the sources I gave you. Don't add outside facts, and don't invent claims, numbers, or sources. Where a source is unclear or two sources conflict, surface it rather than smoothing it over. Attribute each point to the source(s) it came from. If the sources are thin on my goal, say what's missing.
