14.7.0

Two editorial/optimization features on top of the per-image quality override from 14.6.0.

Per-image compression report

The file metadata form now shows, right below the compression quality field, what each enabled format achieved for that image: per processed variant (each rendered size), the generated WebP / AVIF / JPEG XL sibling's size and the saving versus the source it replaces. Read-only; it fills in as the image is rendered at more sizes.

Compress larger variants harder

Optional per-format width-to-quality curves (quality_by_width, quality_by_width_avif, quality_by_width_jxl) map a rendered variant's width to a quality, so larger variants are compressed harder automatically — the responsive-image best practice (a large hero that produced no smaller WebP at the global quality now does). Off by default; a per-image quality override still wins, and lossless parameters are left untouched. The README has a copy-paste recommended starting curve.
