SVG path optimizer

Ties between the absolute and relative form keep the absolute one, and H/V counts as the absolute form. Curves written with S and T shorthands are expanded to C and Q with the reflected control made explicit, so the output never depends on renderer state reconstruction. This tool does not sanitize: scripts, event handlers, and editor namespaces pass through untouched, and the previews below render through image elements, which cannot run them. Treat a pasted file as untrusted until you have reviewed it.
