/* Deep Dive 5 - hover glossary.
 * A math word gets a dotted underline. Hover it, tab to it, or tap it, and the
 * definition appears. This replaces writing the definition inline every time, so a
 * problem can read as a plain question instead of a paragraph of parentheticals.
 * Scoped to .dd5-term* so nothing else is affected.
