 Worlds declare their default (`defaultViewMode: stage`); you can switch any time in-session.

+![A dice check, quest progress, and a gear change posting into the turn, with the quest log open alongside](./.assets/images/readme/rpg-systems.png)
+
+A risky action resolves against dice rolled **before** the narrator writes, so the outcome cannot be retconned to fit the prose — and the arithmetic posts inline: `19 + 2 = 21 vs DC 16`. Quest progress, gear changes, and affinity shifts land in the turn the same way, then accumulate into their own panels. Dice, quests, inventory, and affinity are four separate plugins; a world seeds the opening quests, starting gear, and initial affinity, or ships without any of them.

+有风险的行动，判定用的骰子在叙事**动笔之前**就已经掷好，结果不会被行文倒推改写 —— 算式直接落在正文里：`19 + 2 = 21 vs DC 16`。任务推进、装备变动、好感升降也以同样方式回执在这一回合里，再沉淀进各自的面板。骰子、任务、行囊、好感是四个独立插件；世界包预置开局任务、初始装备与初始好感，也可以一个都不装。
