/**
 * @fileoverview Authentication mode constants.
 *
 * Why a dedicated module: Lovrabet Runtime CLI only supports `client-ak` (AccessKey)
 * authentication. Defining `AUTH_MODE.ClientAk` as a typed constant ensures:
 * 1. Every place that checks or sets the auth mode compares against the same string.
 * 2. If a new auth mode is added in the future, callers using `AUTH_MODE.ClientAk`
 *    will continue to compile correctly, and only new call sites need updating.
 * 3. `AuthMode` as a type alias makes it easy to narrow and validate values.

 * Auth mode supported by Lovrabet Runtime CLI.

 * Why not a union type inlined everywhere: if auth modes expand (e.g. `"user-session"`),
 * we only add one entry here. Call sites using `AUTH_MODE.ClientAk` are already
 * written to be swapped out if needed.
