Idea

When a Toggle card is created (even by rform in multi-edit), it has no content, but is treated as a zero. If you edit it on it has a 1, and off it has a 0. Thinking consistency would be of value here, maybe give it a content of 0 when it's first created. Workaround for right forms is to edit it to yes then no.

Separate question is whether numbers make sense (vs. "yes" and "no", or...?). Probably fine, as long as we treat it as a Number card in code where relevant.
