#
# This script uploads a small test image to the T3 API.
#
# The endpoint accepts an image file via multipart/form-data and returns
# an imageFileId that can later be associated with an item.
#
# The script will:
#   1. Authenticate you with the T3 API
#   2. Let you pick a license to work under
#   3. Generate a tiny 1x1 pixel PNG test image in memory
#   4. Upload it to POST /v2/items/images/file
