/**
 * Image Hover Assist — front-end styles.
 *
 * A single image with a selectable hover effect, overlay, badge, caption,
 * description, button and an optional lightbox. Effects are CSS-driven; the JS
 * engine (hover.js) only adds spotlight, ripple and the lightbox.
 *
 * The "hovered" state is `.dia-hover-image-wrap:hover / :focus-within` (no-JS
 * friendly) plus `.dia-hover-active` which hover.js toggles for the click trigger.
