“SVG download came back as PNG”

I used OpenRouter's image/file output flow during a design-model test and downloaded what should have been an SVG. The file workflow produced a PNG-style save instead, and then the SVG I tried to send/load did not render correctly on the other side. The result was a tiny but maddening integration bug: the model output may have been useful, but the file handling made it feel like I was debugging the delivery wrapper instead of judging the design.
