/*
 * theology.techatpt.com — a filing drawer of index cards.
 *
 * One drawer, pulled open. Behind the main card, a stack of tabbed cards
 * rises toward the back (the division, the apps); in front of it, a lower
 * stack holds the paperwork (privacy, terms, refunds). A tab is a link; the
 * card it belongs to slides into the main slot. Everything is drawn with
 * borders, not images, so it prints like the paper it imitates.
