/*
 * Hungry Pathing: the project site. The works canteen at a timber mill: meals and water timed to the shift whistle,
 * a slate board that says when to leave so nobody works hungry, and enamel signs that point to the nearest canteen.
 * Cobalt-and-cream vitreous enamel, blue-black slate with chalk, the mod's own coral for Hunger and a water blue for
 * Thirst, on a sawdust-grey works yard by day and a sooty timber shed by night.
 * Textures are produced by assets/textures/make_textures.py. Big Shoulders Display is self-hosted (assets/fonts/, OFL).
