# VERTICAL SLICE - NOT FOR PRODUCTION
# 局内暂停层·只读（迭代 17 卡③ 暂停层只读入口批 2026-10-06——任务书 v1.1；事实源=06-待办清单
# 「解锁界面与钥石呈现的交互形态（残余：暂停层只读入口）」）。
# 裁决落形：P1 丁=入口为战斗屏 HUD / 关卡地图屏常驻角标（入口装配在 ui_assembler/两屏，本类不含入口）；
# P2 甲=登记 modal_stack 设置层同档（确认弹窗之前）带 dim 遮罩；P3 甲=展示钥石余额+三柜台进度
# （属性锻造三行已购等级 / 道具工坊六件解锁态 / 天赋树已购概览——层内行序与分组复用营地屏同序）；
# P4 甲=进出零动效直开直关（无 tween 无 AnimationPlayer——R5）。
# 只读契约：R4 数据只读同源——账面快照由组合根 open_pause 喂入（每次开层实时读 MetaProgression
# 访问器重建，快照仅用单次开层生命周期，跨开层零持有）；本类零核心访问、零写通路——唯一信号
# closed（关闭意图，组合根经模态栈单口收口）。R1 公共件单点：全部构成件经 UiKit 工厂产出
#（modal_shell/panel_skinned/label/button/keystone_badge），零裸色值零自建样式。
