/* File Field — canonical Direct Upload primitive.
   Drives the file_upload Stimulus controller (Active Storage Direct Upload).
   Promoted from `experience_editor/elements.css` (.ee-file-upload__*).

   Anatomy:
     .file-field                         (controller wrapper)
       .file-field__input                (visually hidden native <input type=file>)
       .file-field__btn                  (initial-state "Upload" trigger)
       .file-field__attached             (current-state row — file present)
         .file-field__file               (left cluster: icon|thumb + filename)
           .file-field__icon             (16px material symbol; OR)
           .file-field__thumb            (32×32 small preview; replaces icon)
           .file-field__name             (truncated filename / caption)
         .file-field__actions            (right cluster: icon-only buttons)
           .file-field__action           (24×24 ghost icon button, swap_horiz / close)
           .file-field__action--danger   (modifier — red hover for Remove)
       .file-field__progress             (inline progress bar during upload) */
