🧾 Notes

sideEffects is set to false - tree shaking will remove all unused parts and will further reduce the size of your final bundle.

Skins are independent of each other. The final bundle size is a sum of common dependencies plus skin size (typically around ~2.5kb with a single skin). Indicative stats on sizes can be found in "stats.html"
