/*
 * Evelyn — a steno pad on a secretary's desk, 1961.
 *
 * The page is the pad: eye-ease green paper, blue rules on a 28px line, and the
 * red margin rule that splits *when* (left of it) from *what* (right of it).
 * Evelyn's own words are typed (Courier Prime); the interface speaks in
 * Franklin, the face of American offices and forms of the period. Pink is the
 * "While You Were Out" slip and means one thing only: this needs you.
