/*
 * The editor chat: the collapsed rail, and the panel.
 *
 * Two shapes, one surface. Shut, it is a 44px strip with the word `Editor`
 * running up it and a 6px dot when something arrived -- reachable, and
 * incapable of being in the way. Open, it is a 320-352px panel on the page
 * background, so it reads as part of the room rather than as a window over it.
 *
 * The asymmetry between the two kinds of turn is deliberate: the author's words
 * are bubbled and right-aligned, the editor's are unbubbled prose under a
 * byline. A reading of the book is not a message, and should not arrive looking
 * like one.
