 The following is an incomplete list of tasks and problems that still need to be resolved:
 
 - [ ] sort out issues with `eval` and MDX and undo edits in `./app/[locale]/[[...path]]/page.tsx`
-- [ ] reimplement `getMarkdownFiles` in `next.helpers.mjs` to be generated at build time
-  - this can be accomplished either via a npm/turbo prebuild task, or possibly as part of next.js SSG/staticProps (but we need to ensure that we don't end up accidentaly downloading this big file to the client as part of hydration)

+  - [ ] we need to ensure that we don't end up accidentally downloading this big file to the client as part of hydration
   - [ ] once we have easy access to the list of files, we should roll back changes to `next-data/providers/blogData.ts`
 - [ ] back out most changes from `next.dynamic.mjs`
   - [ ] instead of using runtime detection via `globalThis.navigator?.userAgent`, we should instead use `alias` feature in `wrangler.toml` to override the implementation of `node:fs` calls but only when running in workerd as we need the build to keep on running in node.js for SSG to work
