# In the paired web client (1280x800, dark), open this thread.
# Wait for the parent to reach the nine-consecutive-block cap.
# Close the thread details panel. Start a browser recording.
# Type `/btw What is 2+2? One word.` into the parent composer and press Enter.
# Wait for the side chat to complete; retain the parent and side chat in view.
# Stop recording. Crop x=256,y=0,width=1024,height=730 to omit sidebar and
# private model selectors, retaining the actual conversation and side-chat panel.
# Historical case: close the side chat, send `/btw` with no question, clear
# the parent's goal, then ask `What is 2+2? One word.` in the empty side chat.
# Parent preservation (supplemental head run): repeat the parent goal and side
# question in a fresh thread; after the side chat ends, send the same arithmetic
# question to the parent. Its goal must still block stopping until the cap.
