Files cached for 1 week for testing
Use the API endpoint: POST /file-upload-api for programmatic testing.
How it works. Files upload as 8 MB parts into the
Workers Cache API (any isolate). Download is one URL
(/f/<id>) that streams parts without holding the
whole file in the 128 MB isolate heap. Cap ~512 MB. Works with
curl -fL -o file.bin 'https://โฆ/f/<id>'.
