 *
 *   text      -> `textContent`   (never `innerHTML`: no markup can be injected)
 *   attr      -> `setAttribute`  (allowlisted names only: no class/style/id)

 * "integration cannot change the design" a property of the code rather than a
 * rule someone has to remember. Adding such a branch is the one change reviewers
 * of this package must refuse.
