/* The help centre.
 *
 * Two ideas carry the whole design. First, annotations live in HTML on top of
 * a raw screenshot rather than being drawn into the pixels — so re-shooting a
 * screen does not mean redrawing anything, a translation touches strings rather
 * than images, and the text an arrow points at is text a screen reader reads
 * out. Second, every annotation's meaning also exists in the step it belongs
 * to, so the whole site works with images off. That is not a nicety here: the
 * people reading this are often on a phone, on a slow connection, between
 * appointments.
