/*
 * Guide — the cards of a guide (Tour) over the page (shared/_guide.html.erb, guide_controller.js).
 * A modal <dialog> as large as the screen: the spotlight is a hole over the element a step talks about, its huge
 * shadow darkening the rest; with no element, the dialog itself darkens and the card sits in the middle.
