/**
 * Choosing where to go next when the model you are on runs out.
 *
 * Rotation used to ask only "which account still works". That is the wrong
 * question when the limit is per model. If a session is on Fable and Fable runs
 * out on this account, the useful move is another account that still has Fable,
 * not any account at all, and certainly not one whose Fable is also spent.
 *
 * Only when NO account has room on the current model is it worth changing model,
 * and then it should be the next one you would actually want rather than
 * whatever happens to be free. Hence a preference order, defaulting to Fable
 * then Opus, and configurable because that order is a matter of taste.
