/* NexDrive shared form controls — loaded by both the customer site and
   the admin tool, after tokens.css and before site.css / admin.css.

   Two components live here because they appear on both surfaces and
   must look the same on each:

     .upload-field  — a drop-zone around a native <input type="file">.
                      Pure CSS gives the styled box; upload.js adds
                      previews, remove buttons and drag-and-drop.
     .combobox      — the type-to-filter select combobox.js builds in
                      front of a <select data-searchable>. Without JS the
                      native select renders instead and none of this
                      applies.

   Everything is token-driven; the surfaces only tweak spacing. */
