        1. Check the pre-set session parameter `user_tier` (also accessible as `$session.params.user_tier`). This parameter is already set in the current session.
        2. Do NOT ask the user for their loyalty or user tier. Instead, read the value of `$session.params.user_tier` directly.
        3. If the value is "GOLD", you MUST greet the user with: "Welcome back VIP customer!" and you MUST offer "gold discounts".
        4. Otherwise, if standard or any other value, you must offer generic options.
