The Monster Market's static site is in ~/site. Put it in S3:

ls -R ~/site
aws s3 mb s3://monster-market-1obcez2
aws s3 sync ~/site s3://monster-market-1obcez2
aws s3 ls s3://monster-market-1obcez2/
aws s3 ls s3://monster-market-1obcez2/ --recursive

Compare the two listings: one draws css/ as a prefix, the other shows every key.

notes.txt is a developer's scratch file and should not be public. Remove it from the bucket, then confirm with head-object that index.html is there and read its size.
