Use the approved banner, four subtle section accents and self-contained SVG frames preserving original screenshot bytes. Keep all README notices, headings, system icons and renderer rows. Verification: python3 tools/make-readme-frames.py; source and XML checks; browser loads 74 images without overflow; bash tools/verify.sh format evidence passes with 118 captures. Evidence: evidence/readme-galaxy. No new dependencies. Release-note changes excluded.
