R2 EU direct checkpoint
Use the existing test login first. Results contain no credentials or signed URLs. Run the small suite, then the private PDF check. The large-file button is optional for this EU repeat.
The small suite creates about eleven tiny test objects. A failure stops the suite; do not proceed to the other buttons until reviewed.
Ready
The large test generates its own bytes and stores 130 MB in the test buckets. No personal file is needed.
