 * a sheet of paper on a table in the afternoon, and a black page would be
 * selling a different game.
 *
 * Everything here is the game's own: the palette is scripts/core/fold_palette.gd,
 * the paper and the cherry branch are the textures the app ships, and the wide
 * tracked uppercase is how the game sets every heading it has.
