/* HYPERPART: tags */
/* dz-tags — HM-native multi-value chips input (HMC-018 slice 2).
 *
 * Progressive enhancement over a real `<input type="text" data-dz-tags>`
 * carrying a comma-joined value: with JS off the native input is fully
 * usable (the user types "a, b, c"; the server splits on comma). Controllers
 * wrap it in a `.dz-tags` root on ready when the value is seeded, otherwise
 * on first interaction — a role=list of removable chips + a borderless entry
 * input — and hide the native input (kept in the DOM as the submit value +
 * no-JS fallback). The
 * `.dz-tags` box carries the input chrome + focus-within ring + aria-invalid;
 * the entry is borderless inside it. Chrome mirrors the combobox /
 * search-select family. */
