I'm working on a simple TanStack Start repo that deploys seamlessly to Railway. I'd like to be able to just enter the URL and https://github.com/jherr/railway-start-simple/blob/main/railway.toml then Deploy but HOST needs to be set to :: and PORT needs to be set to 3000. Is there a way to make this more seamless? I honestly don't care about specific environment variables per se. I'm just interested in reducing the configuration work to zero.
