Is this intentional? As a simple example of what I mean, if you do this: ```bash export DICTIONARY_KEY=foo-123 cargo build export DICTIONARY_KEY=bar-456 ./target/debug/defrs ``` Then the API key that gets used is `foo-123`, *not* `bar-456`. By setting the API key at compile time - users share API keys if they share binaries - users need to recompile the binary if they want to change the API key
