 - **`MAX_FILE_SIZE_MB`** (default `50`) — rejects uploads exceeding this size. Validated at two levels: early `Content-Length` check and streaming byte count.
 - **`MAX_PAGE_COUNT`** (default `0` = unlimited) — rejects documents with more pages than allowed. Useful on shared instances or Hugging Face Spaces to cap processing time.
-- **`NGINX_MAX_BODY_SIZE`** (default `200M`) — nginx-level body cap, applied before the request reaches the backend. Defaults to `200M` so `MAX_FILE_SIZE_MB` is always the effective limit. Use nginx format (`50M`, `1G`, `0` for unlimited).
