# Museum Exhibit Studio - learner entrypoint.
#
# HOW TO EDIT THIS FILE
#
# Every place you write code is a named region between two marker lines:
#
#     >>> BEGIN <region> | Step 4: INSERT | Step 6: REPLACE
#     <<< END <region>
#
# The BEGIN line lists every step that touches the region. Each lesson block names its region
# and one of two actions:
#
#     INSERT   The region is empty. Paste the block between the two marker lines.
#     REPLACE  The region already has code. Delete everything between the marker lines,
#              then paste the block.
#
# A block is always the complete contents of its region. Never edit, move, or delete a marker
# line, and leave the code outside the regions as it is.
#
# The pre-built curator helpers live in curator.py, and the system messages in
# system_messages.py. Do not edit those files: they are the application-owned half of the
# workshop, and they must stay identical to the finished app's copy.
