⚙️ Batch Chroma Subsampling, Quantization & Core Web Vitals Optimization

Unoptimized images are the primary bottleneck failing Google's Core Web Vitals Largest Contentful Paint (LCP) threshold. High-resolution camera sensors embed megabytes of high-frequency chroma noise and EXIF metadata that add zero visual value on web viewports.

DH Tools processes dozens of images concurrently in local browser memory: applying perceptual quantization tables, optional dimension capping, and instant ZIP bundling to cut page weight by up to 85%.
