/* literature-inferno.css
 *
 * Scoped to the Map of Hell page. The page chrome matches the rest of the
 * site (Fraunces + Inter, the Literature green). The map itself sits on a
 * dark stage, because it reads better on a projector and because the
 * subject asks for it.
 *
 * The band colors run warm at the top, hot through Dis and Violence, and
 * cold at the bottom. That is Dante's own arrangement, not decoration.
