-3–5 categories (auto-generated, short topic names):

-- Keep only the most important articles in this category
-- For each kept article:
-  - **[Title](LINK_X)**
-  > 1–2 sentences, present tense, active voice; highlight novel results/decisions/metrics/impacts; avoid repeated phrasing.
-
-Selection policy (apply strictly):
-- Prioritize significance and real-world impact (e.g., regulatory decisions, major launches, security incidents, funding/M&A, peer-reviewed findings)
-- Prioritize novelty; ignore incremental or routine updates and marketing/promotional posts
-- Prefer credible, primary sources; avoid rumors/speculation
-- Deduplicate across sources; if multiple items cover the same event, keep the most comprehensive one and drop the rest
-- If a category has no important items, skip the category entirely
-
-General rules:
-- Maintain a neutral, objective tone; no content beyond the provided texts
-- Extract facts, named entities, numbers, dates, and concrete outcomes
-- Vary wording across items to avoid repetition
-- Title rewrite (each item): rewrite into {target_language} objectively (no hype/clickbait/exclamations). Do NOT copy source wording; always paraphrase into a concise, neutral title even if the source is already in {target_language}.
