/**
 * When we run a vite prod build it creates a folder in the output dir called assets in which
 * every file includes a hash of its contents in the filename. These files include files that
 * are 'imported' by the js bundle, e.g. svg and css files, along with the js bundle itself
 * (split into chunks).
 *
 * By default, when we deploy a new version of the app it will replace the previous versions
 * of the files with new versions. This is problematic when we make a new deploy because if
 * existing users have tldraw open in tabs while we make the new deploy, they might still try
 * to fetch .js chunks or images which are no longer present on the server and may not have
 * been cached by vercel's CDN in their location (or at all).
 *
 * To avoid this, we keep track of the assets from previous deploys in R2 and include them in the
 * new deploy. This way, if a user has an old version of the app open in a tab, they will still
 * be able to fetch the old assets from the previous deploy.
