Sudden build failure

Updated a README and pushed and was surprised that my build is now failing.

looks like service is still live though another push and healthy again. Resolved.

Looks like you're on Heroku buildpacks btw. Any reason you haven't moved to Nixpacks yet?

Moved from heroku to railway and wanted to keep my initial workflow at the time - especially knowing that I could likely also shift to other services like fly.io if I determined I needed their feature set. But no worries, I'm having a good time on railway and have no plan of moving off platform. I'll get around to moving to nix packs probably when railway gives me a pop-up saying my heroku config will start failing
