Each config array can now have its own resolution list displayed as chips with categorized preset dropdown (SD 1.5/SDXL/Flux × Square/Portrait/Landscape) plus custom W×H input. Resolutions flow through configs_json, expand in the Cartesian product, and override the sampler's global resolutions_json on a per-config basis.
