/* ── dv-fileupload ──────────────────────────────────────────────────────────
   Custom design-system file upload. Progressive enhancement of a native
   <input type="file">: the native input stays in the DOM (source of truth for
   submit / direct-upload) and is visually hidden; this drop zone + file rows
   are layered on top and kept in sync by the fields--file-field controller.
   Ported from tmp/form-elements-preview.html (.dv-upload / .dv-file). Token-only.
