[cost\_intel] OpenAI vision high-resolution mode costing 9× more tokens than low-res for identical image

Force 'low' resolution for all images unless OCR of fine print \(<12pt\) is required; a 1024×1024 image costs 765 tokens \(high\) vs 85 tokens \(low\). Use 'detail': 'low' in the image\_url object.

Journey Context:
OpenAI's vision pricing isn't per-pixel but per 512×512 'tile' for high-res mode. A 1024×1024 image is split into 4 tiles \+ a base 85 tokens = 765 tokens. Low-res mode is always 85 tokens. Agents defaulting to 'auto' or 'high' for UI screenshots burn 9× tokens with zero quality improvement for charts or text >12pt. The quality degradation signature only appears on tiny fonts.
