Every time the bot presents choices to the user, it MUST automatically color each button based on how critical, irreversible, or different the choices are. The bot never sends plain/unstyled choice buttons — color is always applied.

每当机器人向用户呈现选项时，必须根据各选项的关键性、不可逆性或差异程度自动为每个按钮着色。机器人从不发送未着色的普通按钮——始终会应用颜色。
