The image endpoint supports size, format, variant, theme, fallback, and version. It never silently returns a favicon as a wordmark or raster content as an original SVG.
Use fallback=monogram only when your interface explicitly accepts generated placeholders. Otherwise the default fallback=404 keeps missing assets distinguishable.
