 * Reapers.
 *
 * One visual world, deliberately: a furnace at night. The page commits to dark
 * rather than offering a light twin, so every colour is painted explicitly and
 * nothing borrows a host background.
 *
 * Three colours do all the work. Furnace black is the ground, bone is the ink,
 * and ember is the only accent - it marks burning and nothing else, so when
 * something on this site is orange it is because supply is being destroyed.
