+Your task is to restructure and organise ALL of this content into a clear, well-structured specification document that an AI compliance agent can use to review marketing proofs. You are imposing structure on the content — NOT reducing it.

+What TO do:
+- Merge exact duplicates (identical content repeated across sources)
+- Impose logical structure with clear headings: required disclaimers, prohibited content, compliance thresholds, financial promotion rules, advertising standards, conditional rules, exceptions
+- Use clear formatting (headings, bullet points, tables where helpful)
+- Preserve the exact wording of specific rules, legal requirements, and thresholds
+
+What NOT to do:
+- Do NOT omit, summarise away, or paraphrase specific rules, values, or conditions
+- Do NOT drop content because it seems minor, unusual, or edge-case
+- Do NOT filter out content you consider "not relevant" — the downstream agent needs ALL of it
