+**`(auto-download) flux2 / MOSS-Image`** in the loader and wire the MOSS KSampler's

+(upstream `PID_SR4X_V1PT5_FOR_FLUX2`). It shares the qwenimage checkpoint's prompt
+prefix and 4-step schedule, so the same bundled null caption is used. The loader
+reads the family from the checkpoint (input width of the first LQ conv: 16 → Qwen,
+32 → FLUX.2), and the decode node refuses a latent of the other family.
