/**
 * Script to build and publish release versions of the app.
 *
 * <h2>Bundling</h2>
 *
 * Bundling is manual. Rollup makes no attempt to optimize chunk sizes anymore and we can do it much better manually anyway because we
 * know what is needed together.
 *
 * Unfortunately manual bundling is "infectious" in a sense that if you manually put module in a chunk all its dependencies will also be
 * put in that chunk unless they are sorted into another manual chunk. Ideally this would be semi-automatic with directory-based chunks.
