she's small as a dog now!
Rollup was previously bundling the minified p5 lib with the compiled js which is totally unnecessary given that p5 is a peer dependency.
Now that's not a problem. The new unpacked size of the build is optimized down to only 26.4 kB.
Just for comparison, it was previously 1.25 MB. That's a whopping 97.89% savings in bundle size!
