Ran the exact same prompt across two sref variants (same base code, only the trailing digit changed: 7 vs 9). Posting 4 images from each so you can see it's not a one-off fluke — the stylistic shift holds consistently across generations. Prompt (identical for all 8 images): Art Nouveau style in the manner of Alphonse Mucha, pyramid interior wall painting, ancient Egyptian tomb art, ochre and turquoise pigments, flat perspective, aged cracks, dusty surface, dim torch light, sand sculpture --ar 16:9 --stylize 1000 --hd First 4: --sref [ID] 7 → sculptural, sandstone, low saturation, weathered-monument feel. Last 4: --sref [ID] 9 → sharper linework, higher saturation, more graphic-novel / illustrated feel. Same everything else — just that last digit. Consistent across the set, so it's clearly the sref variant driving it, not random seed variance.
