+// This bundles all the imports that are used in the `index.ts` file. They are

+// `index.html` as small as possible, so it can focus on requesting the WASM
+// file as soon as possible. This should result in the `indexDelayed.ts` bundle
+// containing basically all the JS. This JS bundle and the WASM file should then
+// be requested in parallel. While it would be possible to request these all
+// individually over in the `index.ts`, browsers don't actually like doing too
+// many requests in parallel and it turns out that big JavaScript files actually
+// compress better than having many small ones. The WASM file also is pretty
+// big, so ideally we are not bottlenecked by the large JS file. If necessary,
+// we could do some more bundle splitting for stuff that isn't used until much
+// later, like the Markdown library.

+// FIXME: Look into pulling even more CSS out of the index.ts as well.
