# VERTICAL SLICE - NOT FOR PRODUCTION
# Date: 2026-09-21（元进度实现批——营地覆盖层呈现；2026-09-30 迭代 9 卡⑭ 视觉终稿——对照营地屏
# 方向稿 artwork/mockups/v3-draft-2026-09-29/4-camp.png 重排：石纹全屏底 + 顶栏铭牌/钥石徽 +
# 三柜台列（属性锻造/道具工坊/奖励格图鉴，头带深棕+米色板身+内嵌行板，暗底→亮板双色墨制）+
# 底栏关闭钮/操作注记；最近冒险收底栏条带。信号面/投影契约零变化：buy_requested(attr)/closed、
# open_camp(data)/refresh_camp(data)、_forge_rows 行结构 {attr,level_l,price_l,btn}（探针依赖）。
# 挂接方式：开合与开始层互斥仿 TunePanel 先例（开始覆盖层非模态且树序在后——打开本层前由组合根
# 隐藏开始层，规范 2.3 遮挡纪律）。
# 高内聚边界：纯视图 setter 面——账本快照经组合根喂入（MetaProgression 只读投影），购买/关闭
# 意图经信号外发——零核心写调用、零 MetaProgression 持有。
