"""Re-emit sip_view.svg in an academic palette (white background, black
strokes) and convert it to PDF for the 1H-codesign-paper Figure 1.

Source of truth: docs/diagrams/sip_view.svg (generated by
src/kernbench/topology/visualizer.py, dark-ish theme).

Treatment per user request: keep the layout intact, just force a white
canvas and turn every stroke black; promote faint label text to black so
all annotations stay legible on white.
