[cost\_intel] Vision API 'high' resolution mode burns 17x tokens on text-heavy UI screenshots

Use 'low' resolution for text/UI screenshots <2000px wide; use 'high' only for detailed photos or charts with <8pt text; calculate: if image is >85% text pixels via OpenCV, force low

Journey Context:
GPT-4o vision pricing: 'low' resolution costs 85 tokens fixed, 'high' resolution costs 85 \+ 170 tokens per 512x512 tile. A 1080p screenshot in 'high' mode tiles into ~8 tiles, costing ~1445 tokens \(~$0.005 at $3.33/million\). The same image in 'low' costs 85 tokens \(~$0.00028\) — a 17x cost difference. For text-heavy UI screenshots, 'low' resolution preserves OCR accuracy >95% because text is high-contrast and large relative to UI elements. 'High' is only necessary for: \(1\) Fine details \(<8pt text\), \(2\) Photographs with complex scenes, \(3\) Medical images. The quality cliff for 'low' appears with antialiased text <6pt or complex diagrams with overlapping elements. The hidden cost: using 'high' for all screenshots in a UI automation agent processing 1000 screens/day costs $5/day vs $0.28/day for 'low' — an 18x operating cost difference for identical information extraction.
