feat(app-iced): M68 —— iced 0.14 骨架（后端探测/字体基座/自绘标题栏/导航轨/深浅主题/截图通道）
新增 crates/app-iced（package `unlucky-app-iced`，bin `unlucky-launcher-iced`），与 Slint 版并存， 为 D26「UI 从头写」打地基。本 mission 只做骨架：能开窗、颜色/字体对、层级在，不做业务页面。 - 后端（D27）：启动探测 wgpu 适配器（只看 device_type，避开 WARP 误判）→ 写 ICED_BACKEND； auto/gpu/cpu 三条路径都保留 tiny-skia 兜底，绝不硬失败；`--renderer=cpu` 跳过探测（省 ~0.85s） - 字体（D28 前半）：令牌三平台字体栈 → 用 iced 全局 FontSystem 查装机情况 → 族名与 400/500/700 字重落点（缺档按 Nearest/Synthetic 记录）打一行启动日志 - 令牌适配层 theme::Ui：唯一把 unlucky-design 的值翻成 iced Color/Font/Border/Radius/Theme 的地方； 49 个 M3 角色留在自己的 Scheme 里，iced 的 6 色 Palette 只给 devtools - 骨架：1180×760 无边框窗口、48 高自绘标题栏（drag + 东/南 drag_resize + 最小化/最大化/关闭）、 88 宽导航轨（56×32 SecondaryContainer 药丸，由令牌推导）、页头 56 + 一张 OutlinedCard - 主题：系统主题探测 + --theme，切主题只重建 Ui（Theme::name 变化触发重算），不动 UI 状态 - 截图通道：`--screenshot <png>` + `--screenshot-theme`（真开窗第 3 帧出图），以及 `--diff <a> <b>` 自带逐像素对比（CI 不依赖 Python/ImageMagick） - 图标：令牌 SVG path → iced svg 控件（颜色走 alpha 蒙版，深浅共用一份位图缓存） - 门禁：tests/no_hardcoded_tokens.rs 扫源码挡色值/尺寸字面量 + 挡 slint 依赖（自检也算过） 实测（Windows Server 2025 / 96 DPI / RX 6600 XT）：浅/深 × GPU/CPU 四张真开窗截图；GPU vs CPU 差异 0.72% 像素、全部落在字形/图标抗锯齿与 1px 圆角描边、最佳对齐 (0,0)、平坦区颜色逐字节相同； release 体积双后端 6.44 MiB / 仅 CPU 3.75 MiB；首帧 GPU 1.18~1.31s、CPU 33~37ms。 未做/未验证：macOS 与 Wayland 全链路、西/北边缩放热区、letter spacing（iced 0.14 无此属性）、 中文 CDN 字体、玻璃；翻牌步骤写在 DevDocs/SubAgentsTalk/app-iced-骨架与翻牌.md（不入库）。

//! 首屏骨架（**不做业务**）：自绘标题栏 + 左侧导航轨 + 内容区（页头 + 一张卡片）。
|
||||
//!
|
||||
//! ## 与参考判据的对应（`research/12b-component-fidelity.md`）
|
||||
//!
|
||||
//! | 部件 | 参考 | 令牌落点 |
|
||||
//! |---|---|---|
|
||||
//! | 标题栏高度 | 16.2 桌面标题栏 **40**（登记偏离） | `LM.titlebar_height = 48`（M63 §1.4/R13 桌面档，令牌优先） |
|
||||
//! | 标题栏按钮 | 16.5 图标 **24** | `IconSize::Toolbar` + `LM.titlebar_button_width = 46` |
|
||||
//! | 页头 | 16.1 官方 AppBar **64**；本项目 **56** | `LM.page_header_height = 56`（已有偏离登记） |
|
||||
//! | 卡片 | 3.x Outlined：**Medium(12)**、L0、`OutlineVariant` 1px、`SurfaceContainerLow` | `Component::OutlinedCard.spec()` + `STROKE_PX` |
|
||||
//! | 字级 | 16.4 标题 `TitleLarge`；卡片 `TitleMedium` / `BodySmall` | `Ui::style` / `Ui::emphasized` |
|
||||
//!
|
||||
//! 导航轨在 [`nav`] 子模块里（12b §5 的判据表也在那边）。
|
||||
//!
|
||||
//! 一屏只出现 4 档字号（22 / 16 / 14 / 12），且**没有实心 accent**（rubric K2：一屏最多一个实心
|
||||
//! Primary，骨架期一个都不要）。阴影只给浮层，骨架里没有浮层，所以**全屏零阴影**（rubric K3）。
