Missing .env.example

What it is

The repository reads environment variables but ships no .env.example documenting which ones it needs.

Why it matters

Setting the project up becomes trial and error against runtime crashes, and the list of required variables lives only in whoever set it up last. Deployments miss variables for the same reason.

How to fix it

Add a .env.example listing every variable with a placeholder and a one-line comment. Validating the environment at startup against the same list turns a missing variable into a clear error instead of odd behaviour.
