Convert a PNG into a real, editable vector SVG — traced client-side, not just wrapped in an SVG container.
Tracing uses imagetracer.js (public domain) running fully client-side: it quantizes the image to the chosen color count, traces the boundary of each color region, and fits smooth curves to the resulting paths. Images are capped at 1000px on the longest side before tracing to keep this fast in-browser.
