Cross-platform weekly digest

Build a weekly stakeholder digest covering both my Google Ads and LinkedIn Ads accounts for the last 7 days. Include: total spend across both, blended CPL/CPA, performance per channel, every win worth flagging (top campaigns, biggest improvements), every risk worth flagging (campaigns hitting budget cap, creative fatigue, audience saturation, etc.), and every high-priority optimization for the coming week — don't cap the lists, rank each section by impact. Format as a brief executive summary, then a more detailed per-channel breakdown.
