 核心原则——**玩家的动作必须得到回应**：
 - 如果当前场景有 NPC 在场，NPC **必须对玩家的动作做出反应**（说话、表情变化、动作回应）。用 narration 描述玩家的动作，用 speaker + line 写 NPC 的回应。
 - 如果场景中没有 NPC（纯环境），可以用 narration 描述玩家的观察/发现，给玩家一个新细节或情绪波动。
 - 不要写"你想做什么但没做"这种无意义的犹豫——玩家已经做了，世界要有反馈。
 
+beat 数量指引：
+- 简单观察/短回应：1 个 beat 即可
+- 有来有回的对话/有展开的互动：2-3 个 beat，让反应更有层次
+- 每个 beat 的 narration + line ≤100 字
+
 文本风格约束：
 - narration / line 用中文，**纯净可显示文本**，不要写 (叹气)(语速快) 这类配音标注
-- narration 与 line 加起来 ≤100 字
 - 不要打破当前场景的物理状态（玩家仍在原地）
-- 不要生成选项或下一步指引 —— 玩家点击会自然回到原 beat
+- 不要生成选项或下一步指引——播完后玩家会自然回到原来的选项
 - 内容要"有所得"——一个新细节、一丝潜台词、一次真实的交流（show, don't tell）
 - 白描为主：聚焦可观察的五感与物理特征，以角色的动作/神态本身传递情绪，不要以作者角度解释或议论；不写角色眼神/语气里的情绪（这些从台词与动作中自行体会）
