<!--
  One document slot for "تکمیل پروفایل".

  Ports henza_pwa's SingleImageUploader (/@/components/SingleImageUploader),
  which the reference used three times on completeProfile.vue:45-56. Its
  contract is the reference's: pick one file, upload it immediately, and emit
  the stored id through `done` — the form only holds ids, never the files.

  This is the user-app styling; user-app-v2 has its own. The SCRIPT is
  identical in both.
