## Summary Follow-up to the PNG-size review feedback on #19320. The three diagrams in the async-compaction post ([blog link](https://hudi.apache.org/blog/2026/07/17/async-compaction-background-maintenance/)) were previously compressed via `pngquant --quality 80-95 --strip`, landing at ~1.4MB total. Voonhous's original comment suggested a ~80% reduction was achievable with pngquant on flat-color diagram PNGs; we were at ~70% off the ~4.8MB original. This PR re-runs the same three PNGs through `pngquant --quality 60-80 --strip --speed 1`, dropping them to ~1.09MB — a further ~23% cut on top of the earlier pass and ~77% off the original payload.
