Abandoned halfway

Two stars, shelved as seen, which is a small lie the shelves are happy to accept — there is no "gave up" status and adding one for a demo would be inventing a vocabulary nobody asked for.

The useful thing here is that the rating and the shelf disagree, and nothing breaks. Metadata on a card is not validated against the shelf it sits on: a renderer that refuses a combination it did not anticipate is a renderer that loses somebody's data the first time they use it in a way you did not plan for.
