"""Standalone example-responses figure (Hivemind-style verbatim callouts).

One probe (C01: "What's your favorite programming language and why?") at
one session position (P5_pre_C6, Sonnet 4.5), showing the filler-arm
(control, judge=3) and claude-arm (drift, judge=0) verbatim responses
side-by-side.

This is a visual template — copy the layout into Fig 1 or use as-is.
