Support fonts etc in Theme Generator

[nileshtrivedi]

Currently the theme generator tool only supports randomization of colors.

It would be great if we can randomize font family, font-size, and variants/margin/padding of components to make them more or less condensed. Ideally, it should be done via a separate button to have a little more control on the theme.

Other potential enhancements would be customizations of gradient/image backgrounds etc. Similar to this Shadcn UI Theme generator: https://gradient.page/tools/shadcn-ui-theme-generator
