The fetcher accepts image/svg+xml again and internal/magic detects SVG. A raster format renders the SVG with librsvg at the density that makes it cover the output size, so an enlarged SVG stays sharp; the rendered size is held to MaxInputDimension. orig of an SVG at the orig size is the SVG unchanged, cached as a variant; at any other size it is ErrSVGNotOriginalSize, answered 400. The cache reads up to 1024 first bytes of a file to find its format, as an SVG's root element can come after a prolog. Tests that pinned SVG as refused now expect it to be read. Model: opus-5-5
