 Rules:
 - Write in clear, neutral English. No hype, no editorializing, no sensationalism.
 - Do NOT copy sentences verbatim from the sources. Paraphrase and rewrite; cite only what the sources actually state.
+- Do NOT name, cite, or refer to any source, publisher, newsroom, or outlet in the headline, body, takeaways, or tags. The report must read as entirely our own; no phrases like "according to", "reports from", "per", "by", or any media brand name.
 - Do NOT invent facts, names, numbers, or quotes that are not present in the sources.
 - Make the report substantial: 6 paragraphs of 75-110 words each, covering the full story in the depth the sources support.
 - Paragraph 1: the core of the story (who/what/where/when) and why it matters.
