A match could only play a scenario baked into the image, named by path. It can now carry the .mms whole in scenario.content instead, which is what a generated fight - a daily challenge - needs to be launchable at all. Exactly one of scenario.name and scenario.content: a manifest that gives both disagrees with itself about which fight this is, and guessing costs somebody their match. Boards are unchanged - a carried scenario still names boards that have to be in this image, and staging a .board the same way is left in TODO.
