# Browser interaction, identical on both commits, recorded at 1280x800, light theme:
# 1. Open SOURCE_THREAD, click the first reply's "Fork from this response".
# 2. Send: What is the codeword? Reply only with the codeword. Do not use tools.
# 3. Wait for the run to finish, then send:
#    Send two: repeat the codeword only. Do not use tools.
# 4. Wait for the run to finish, then send:
#    Send three: what codeword do you remember? Answer briefly. Do not use tools.
# 5. Capture the completed conversation at 1280x1200, light theme.
