/*
 * Presenter cockpit.
 *
 * Dense and glanceable, not pretty. The speaker is standing in front of a room
 * and needs to read this in a glance: current slide, what is next, their notes,
 * how long they have been talking, and whether the room can see them.
 *
 * Keyboard-first, because a speaker with a clicker or arrow keys should never
 * need the mouse.
