optimize build size
our production build is currently 1.7 megs. only 600k-ish gzipped, but still, it's crazy that we're reasonably measurable in megs.
yarn build:analyze
now uses source-map-explorer to analyze our build size.
easy optimization: 23% of our build size is duplicate modules between www and core: firebase, lodash. figure out how to remove the dupes.
