+### 4.7 Image uploads (presigned MinIO)
+
+Every image field (`ProductCategory.icon`, `Product.image`, `StoreCategory.icon`, `Store.logo`, `Store.cover_image`) is a **MinIO object key**, not a Django-served file. Uploading is a two-step flow — the backend never receives the file bytes:
+
+1. `POST /api/media/presign/` (auth required) with `{"filename": "photo.jpg"}` → `201 {"upload_url": "...", "object_key": "uploads/<uuid>.jpg"}`. `upload_url` is a presigned MinIO `PUT` URL valid for 30 minutes.
+2. Upload the raw file bytes directly to `upload_url` (a plain `PUT`, no auth header, no JSON body — just the file as the request body).
+3. Send the `object_key` from step 1 as the field's value in the resource's create/update body (e.g. `{"logo": "uploads/<uuid>.jpg", ...}` on `PATCH /api/v1/seller/store/`).
+
+On read, every serializer that has an image field also returns a `<field>_url` sibling (`icon_url`, `image_url`, `logo_url`, `cover_image_url`) — a freshly presigned `GET` URL valid for 1 hour. Always re-fetch the resource (or re-request) rather than caching these URLs past an hour; they expire.

 - The backend ships a management command that seeds a realistic dataset: 3 cities, 13 neighborhoods, ~19 stores across 6 categories, ~370 products, 30 customers with addresses, 150+ historical orders in every status (placed/preparing/delivered/cancelled), and reviews. Ask backend to run `python manage.py seed_demo_data` (or `--flush` to reset it) against your dev environment before you start wiring up screens — there's no need to hand-create fixtures.
-- Swagger UI (`/api/swagger/swagger-ui/`) is grouped into the same sections as this doc (Locations, Stores, Catalog, Cart, Checkout, Orders, Reviews, Notifications, and the `Seller · *` groups — `Seller · Wallet` and `Payments` only appear on `feature/payment`) — use it to try requests once you have a token.

 - `GET /api/health/` needs no auth and is useful as a "is the backend even up" smoke check.
 
 ## 9. Known gaps to flag back to backend if you hit them
 
-- No multipart/image-upload endpoint yet for store logo/cover or product images (JSON `PATCH` bodies can't set binary fields).
 - No store-approval endpoint — new stores sit in `status: "pending"` until changed via Django admin.
 - No admin/public endpoint to see a store's `service_neighborhoods` from the customer-facing store serializer (needed if you want to pre-warn about delivery coverage before checkout — see §6.1).
 - The `ipg` online-payment callback contract (`/api/v1/payments/ipg/callback/`) is a best-effort integration pending confirmation against a live `ipg` environment — if online payments seem to hang in `pending`, that's the first place to check.
