 * __`SERVER_LIST_URL`__: When set, both frontend designs load their server list from this URL instead of the generated or mounted `server-list.json`. This is useful if you want the containerized frontend to consume a remote shared server list.
 * __`TELEMETRY`__: Whether to enable telemetry or not. If enabled, you maybe want your data to be persisted. See below. Default value: `false`
 * __`ENABLE_ID_OBFUSCATION`__: When set to true with telemetry enabled, test IDs are obfuscated, to avoid exposing the database internal sequential IDs. Default value: `false`
-* __`OBFUSCATION_SALT`__: The salt string that is used to obfuscate the test IDs. The format shoud be a 2 byte hex string (e.g. `0x1234abcd`). If not specified, a random one will be generated.
