  }'
# → {"code":200,"data":[{"task_id":"task_01KQVZAPBW...","status":"submitted"}]}

# 2. faça polling até SUCCESS (cerca de 30–60s)
curl -sS "$HOST/v1/midjourney/task_01KQVZAPBW..." -H "Authorization: Bearer $KEY"
# → SUCCESS, com grid_image_url + 4 image_urls + buttons(U1-U4 / V1-V4 / 🔄)

# 3. upscale escolhendo a 2ª imagem (composição local, SUCCESS em milissegundos)
curl -sS -X POST "$HOST/v1/midjourney/generations/upscale" \
  -H "Authorization: Bearer $KEY" -H "Content-Type: application/json" \

# → {"data":[{"task_id":"task_03_inpaint...","status":"modal"}]}
#   note status=modal, a tarefa espera você completar a mask; timeout de 30 minutos faz CANCEL automático + reembolso

# 2. o frontend desenha a mask (transparente=área a redesenhar, branco=preservar), faz upload no seu próprio OSS e obtém a mask_url (deve ser acessível publicamente)

# 3. submete modal para completar
curl -sS -X POST "$HOST/v1/midjourney/generations/modal" \

# gera direto, sem mask (Outpaint / CustomZoom não entram em MODAL)
curl -sS -X POST "$HOST/v1/midjourney/generations/zoom" \
