upload-limits.txt
My <stack> app on <host> needs to accept uploads up to <size>. Bigger
files fail, sometimes silently.

Tell me every limit in the way, in order:
- The language runtime's upload and request size limits.
- The web server's limit.
- Any proxy or platform limit in front of it.
- Timeouts that cut off slow uploads.

For each: can I change it on this host, and exactly how? If the total
can't reach <size>, show me how to upload straight to object storage
instead, so the file never passes through my server.

Several limits apply at once and the smallest one wins. Raising one of them and not the others produces an error that looks exactly the same.
