/*
 * Sangue e neve: cold white paper, blood crimson and the deep petrol of a
 * church's night, over falling snow. Made for a Vileborn campaign, from the
 * colours of the Apocrypha manual; fits any dark, wintry, gothic one.
 *
 * Suggested with heading_font: Cinzel, text font EB Garamond, and
 * title: centered.
