// lays out the same on every platform (no pointers or heap inside the structs; see Attack and FixedList), so most of it
// goes as it sits in memory, and the few lists as a count and their items. It starts with a layout signature (the sizes
// of everything), so a build that lays things out differently refuses it rather than loading garbage. The menu and
// everything else this screen alone sees isn't part of it, nor is the bots' map of the world, rebuilt on loading.
