Generate width- and DPR-based variants with srcset/sizes and art direction for different breakpoints.

Generate width- and DPR-based variants with srcset/sizes and art direction for different breakpoints.

This approach allows the browser to choose the most appropriate image based on screen size and resolution.

Define target widths per breakpoint (mobile, tablet, desktop, large displays). Limit to key sizes to keep bundle small.
