+R2 domyślnie prywatny. Upload zadziała, ale obrazy się NIE wyświetlą (403),
+dopóki nie skonfigurujesz publicznego odczytu przez custom domenę. To proces
+w Cloudflare (nie w kodzie), wieloetapowy — poniżej dokładnie.
 
-1. Cloudflare → R2 → bucket → Settings → **Public access** → podłącz custom domain
-2. Albo serwuj przez Cloudflare CDN / własną domenę
+### Dlaczego custom domena, nie „r2.dev"
 
-Bez tego media wgrają się do R2, ale front nie pokaże obrazów. Konfiguracja domeny
-jest po stronie Cloudflare, nie kodu.
+R2 oferuje szybki publiczny URL `*.r2.dev`, ALE:
+- jest rate-limitowany (nie do produkcji)
+- nie przechodzi przez cache Cloudflare (brak CDN, wolniej, drożej)
+- brzydki URL (nie Twoja domena)
+
+Dla produkcji ZAWSZE custom domena (np. `media.klient.pl`) — daje CDN, cache,
+własny URL. r2.dev tylko do szybkiego testu.
+
+### Warunek wstępny: domena w Cloudflare
+
+Custom domena dla R2 wymaga, żeby domena (albo subdomena) była zarządzana przez
+Cloudflare (nameservery klienta wskazują na Cloudflare). Jeśli domena klienta
+jest u innego rejestratora — trzeba ją najpierw dodać do Cloudflare (Add Site)
+i przełączyć nameservery. Sama subdomena `media.klient.pl` wystarczy, jeśli
+główna domena jest już w Cloudflare.
+
+### Krok po kroku — podpięcie custom domeny
+
+1. **Cloudflare Dashboard → R2 → wybierz bucket**
+2. Zakładka **Settings** → sekcja **Public access** → **Custom Domains**
+3. **Connect Domain** → wpisz subdomenę, np. `media.klient.pl`
+4. Cloudflare automatycznie doda rekord CNAME (bo domena jest w Cloudflare) i
+   wystawi certyfikat SSL. Poczekaj, aż status = **Active** (kilka minut).
+5. Od tej chwili pliki są publiczne pod `https://media.klient.pl/<klucz-pliku>`.
+
+### Krok: ustaw publiczny URL w projekcie
+
+Payload musi generować URL-e mediów wskazujące na custom domenę, nie na endpoint
+S3. Dodaj zmienną i przekaż ją do adaptera:
+
+```bash
+# .env
+R2_PUBLIC_URL=https://media.klient.pl
+```
+
+Adapter `buildR2Storage` czyta ją i ustawia jako bazowy URL mediów (jeśli
+ustawiona). Bez niej Payload zwróci URL wskazujący na prywatny endpoint S3 →
+403 na froncie. (Patrz aktualizacja buildR2Storage niżej.)
+
+### Weryfikacja
+
+1. Wgraj obraz w panelu (Media).
+2. Sprawdź URL obrazu w panelu — powinien być `https://media.klient.pl/...`,
+   NIE `https://<account>.r2.cloudflarestorage.com/...`.
+3. Otwórz URL w przeglądarce — obraz się pokazuje (nie 403).
+4. Na froncie `<img src>` działa.
+
+### Częsty błąd: 403 mimo custom domeny
+
+- **URL wskazuje na endpoint S3, nie custom domenę** → brakuje `R2_PUBLIC_URL`
+  albo adapter jej nie używa. Sprawdź URL w panelu.
+- **Custom domena nie Active** → poczekaj na SSL/CNAME w Cloudflare.
+- **Public access wyłączony** → w bucket Settings sprawdź, czy custom domena jest
+  podpięta (nie tylko utworzona).
+
+Bez tego media wgrają się do R2, ale front pokaże 403. Konfiguracja domeny jest
+po stronie Cloudflare, publiczny URL po stronie projektu (.env).
