Summary

Replace the small compression table in the root README with the checked-in benchmark summary figure.

What Changed

• remove the three-row compression table from README.md
• embed benchmarks/summary.svg in the root README instead
• tighten the benchmark figure layout by removing the standalone title/subtitle and shrinking the outer margins
• regenerate benchmarks/summary.svg from benchmarks/plot.py
• keep the surrounding benchmark validation and full-benchmarks link intact

Why

The benchmark figure now summarizes both minify-only and minify-plus-wheel compression more effectively than the old table snippet, and the tighter layout fits better as an inline README graphic.

Impact

• the top-level README presents the benchmark summary visually instead of as a partial table
• the embedded figure wastes less vertical space in the README
• readers can still jump to benchmarks/README.md for the full detailed tables and validation notes
• no runtime package behavior changes

Validation

• ran python3 benchmarks/plot.py
• ran xmllint --noout benchmarks/summary.svg
• ran git diff --check
