/**
 * Confirmation dialogs, on SweetAlert2.
 *
 * Delegated on document rather than bound to the links present at page load, so
 * that confirm-link also works on markup injected by an ajax modal.
 *
 * Per-link copy comes from data attributes, all optional:
 *   data-confirm-title   heading            (default: "Are you sure?")
 *   data-confirm-text    body               (default: none)
 *   data-confirm-button  confirm label      (default: "Yes")
 *   data-confirm-icon    warning|error|question|info|success
 *
 * A link whose classes mark it destructive (text-danger) defaults to a red
 * confirm button and a warning icon, so the 92 delete links read as dangerous
 * without touching any of them.
