Additional context

No response

Start with the linked reproduction project and reproduce the failure using Next.js v15, then trace handling of app/icon.svg through next-metadata-image-loader during next dev and next build. Done means the project runs without the invalid-image error, matching the reported Next.js v14 behavior.
