/*
 * The viewer's chrome — deliberately not the report's.
 *
 * The report renders in lockrot's own teal on paper. This page is slate and ochre, with the
 * document sunk into a stage that has a visible edge, so that "lockrot says this" and "the
 * document you were sent says this" never read as one surface. That separation is a security
 * property, not a style choice: the one thing a viewer cannot escape is that it draws a stranger's
 * text under a domain people trust, and the least it can do is never lend it the house style.
