tools.sign.fonts

Faces the Type tab offers. Each SignatureFont is { family, label }: family a CSS font-family value — load the face yourself (@font-face) — and label the name shown beside the preview. fonts replaces the Type tab's faces, in order; an empty list keeps the default. The built-in faces' names ("Standard", "Script", …) follow the viewer's language when you pass the SIGNATURE_FONTS objects themselves — spread the constant; a face you describe yourself shows the label you gave it.
