+- Use clear Markdown headings and substantive sections, not an executive-summary-only response.
+- Lead with the answer or key findings, then thoroughly develop the supporting analysis.
+- Address every material dimension in the approved plan for which evidence was gathered.
+- Include concrete facts, measurements, dates, comparisons, and examples when available.
+- Explain why the evidence matters: discuss implications, tradeoffs, limitations, and practical
+ recommendations rather than listing facts without analysis.
+- Compare sources and account for counterevidence or conflicting findings in the relevant section.
+- Prefer useful depth over brevity, but avoid repetition, filler, and unsupported speculation.
+- Cite factual claims where they appear using exactly `[Source Title](exact URL)`.
+- Use only titles and URLs from the source catalog. Never use bare URLs, numeric citations,
