/* 復古遊戲畫質升級指南 - an AV input menu.
 *
 * Near-black panels, a phosphor-green accent and a faint scanline texture on
 * the header only: the look of the on-screen menu of a scaler, which is the one
 * interface every reader of this site has stared at in frustration. Topics are
 * numbered like inputs (IN1, IN2...). The article body stays light and plain,
 * because long Chinese text on a dark ground is tiring to read and the chrome is
 * the only place the theme needs to speak.
 *
 * Han text wants more leading than Latin, so body copy is set at 1.9.
