Universal Share-Alike Licensecopyleft across different kinds of work

In any number of conversations, I’ve pointed out that a share-alike or “copyleft” license could apply across different kinds of work. For example, a software license could require sharing alike of artwork made with the software. A license for digital artwork could require sharing alike of software incorporating that artwork.

Here’s a sketch of actual terms from my GitHub repository:
