Here is our project brief context in `PRODUCT_BRIEF.md`: Platform is PC/Steam, target market is North America, session length is 30 minutes, subgenre is deckbuilder strategy. We do not have `SOURCE_BIBLE.md` yet. Please draft `concepts/CONCEPT.md` by filling in a dark fantasy lore setting.

游戏概念设计

决定做成什么游戏，不写代码、数值表或逐场关卡脚本。

读取 concept-method.md。输入必须包含 SOURCE_BIBLE.md 与 PRODUCT_BRIEF.md；缺任一项就停止并说明缺口，不代替上游补写。

产物语言由 PRODUCT_BRIEF.md 锁定；未锁定时跟随对话语言，不默认产出中文。

决策边界

直接继承 brief 已锁的平台、输入、受众、分级、时长、目标市场和非目标；发现它们与原作明显冲突时回总入口修订，不在概念阶段静默改值。原作语言、文化语境、目标市场和界面语言分别处理，不从其中一个自动推出另一个。

先例只用于解释玩法为什么可识别：选一个最接近核心动词与循环的主要玩法先例，必要时再补一个解决独立问题的辅助先例。写清借用的动词/循环/结构与明确不借的内容，不要求销量数字、固定名单或为每个方向重复市场研究。外部事实只有在会改变选择且可能变化时才核实。

互动叙事是成熟玩法，不因以阅读和对白承载就降低标准；它的动词可以是读局面、追问、比对信息、表态、隐瞒、交出与承担回响。先例提供语法，原作规则负责改变动作对象、顺序、代价和世界回应，不能只做 IP 换皮。

概念还要判断验证形态：可用成熟交互语法表达时说明“已有语法 + 原作如何改变它”；核心依赖实时手感、空间、视线、物理或独特操作时明确走自定义灰盒。不要把文本原型当所有体验的统一前置层，也不要因有模板可用就让模板替原作决定玩法。

三个方向

先列 brief 的锁定维度和仍开放的维度。三个方向必须在至少三项开放维度上真正不同，例如玩家身份、子类型、核心循环、压力来源、原作选段、空间/镜头、成长关系或美术方向；已锁的主玩法不可偷换，未锁的核心循环可以正面比较。

每个概念卡只回答：

player_job：玩家以什么身份长期做哪份工作，想获得什么独特幻想；
recurring_job_loop：这份工作每个周期反复做什么；
主类型、experienceProfile、主要玩法先例，以及本作借什么/不借什么；
3–5 个核心动词、循环、压力、失败和世界响应；
signature_command：只有当自然语言表达本身能体现该身份时，写 id、label 与候选 intents；
