WHY IT NEEDS A POLICY

Why simplify_svg needs a policy

This tool modifies an existing SVG by reducing/quantizing its color palette. It creates a modified version of the data (Write), but does not irreversibly delete the original unless it overwrites in place. The blast radius is medium since it could alter the appearance of SVG assets if misused.
