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）。

//! Elm 三件套：`State` / `Message` / `update` + `view` 接线。

|

|
//! ## 启动序列（顺序有讲究）
|
||||||
|
//!
|
||||||
|
//! 1. **探测渲染后端** → 写 `ICED_BACKEND`（必须在 `run()` 之前，M60 Q1）；
|
||||||
|
//! 2. **求值字体栈**（D28 前半）→ 一行启动日志；
|
||||||
|
//! 3. `iced::application(..).run()`：窗口 1180×760、无边框（自绘标题栏）；
|
||||||
|
//! 4. 首个 `view()` 打「到首帧」耗时；截图模式下第 3 帧 `window::screenshot` 落盘后退出。
|
||||||
|
//!
|
||||||
|
//! ## 为什么截图要等 3 帧
|
||||||
|
//!
|
||||||
|
//! 无边框窗口启动时会先收到一次「显示器工作区尺寸」的 `Resized`，再回到设定尺寸（M60 坑 #5），
|
||||||
|
//! 第一帧可能是旧尺寸；再叠上字体系统首次上屏的排版抖动，留 2 帧余量最稳。

//! 字体基座（D28 前半）：把令牌的字体栈求值成「本机真的有的族名」，并打一行启动日志。
|
||||||
|
//!
|
||||||
|
//! ## 做什么
|
||||||
|
//!
|
||||||
|
//! 1. 取 `Platform::current()` 的三条栈（Display / Text / Mono，见 `unlucky_design::typography`）；
|
||||||
|
//! 2. 用 iced 的**全局字体系统**（`iced_graphics::text::font_system()`，即 cosmic-text 的
|
||||||
|
//! `FontSystem`，首次调用会扫系统字体）核对每个族名是否装机 → 取栈里第一个装机可用的族；
|
||||||
|
//! 3. 给出 400/500/700 三档字重的落点（原生 / 最近档 / 合成加粗）：
|
||||||
|
//! **先查系统里这个族真实提供的字面（fontdb 的 `FaceInfo.weight`）**，查不到才回落到令牌的
|
||||||
|
//! 纯函数 `Platform::resolve_weight`。缺档按降级记录。
|
||||||
|
//!
|
||||||
|
//! ## 为什么要真查系统
|
||||||
|
//!
|
||||||
|
//! 令牌栈写的是「Win11 有 Segoe UI Variable Text」，但 Win10 / Server 只有 `Segoe UI`（静态
|
||||||
|
//! 300/400/600/700，**没有 500**），干净安装的 Linux 可能一个都没有。只按栈头写死族名会把
|
||||||
|
//! 「实际使用哪个族、哪一档字重」变成猜测——本 mission 的开发机就是 Windows Server 2025，
|
||||||
|
//! 实测就回退到了经典 `Segoe UI`（见交接文档的启动日志）。
|
||||||
|
|
||||||
|
//! ## 不做什么
|
||||||
|
//!
|
||||||
|
//! **中文字体 CDN 下载不在这里**（后续 mission）。本模块只做「系统字体优先」这一半，
|
||||||
|
//! 也没有能力判断 CJK 字形覆盖（那是 `ttf-parser` 查 cmap 的活，M60 Q3 的 spike 做过）。

//! # unlucky-app-iced · iced 版桌面壳（P4 / D26）
|
||||||
|
//!
|
||||||
|
//! 本 crate 是「UI 从头写」的第一步：**只做骨架**（能开窗、颜色/字体对、层级在），
|
||||||
|
//! 业务页面、组件库、i18n 全文案、玻璃 shader 都是后续 mission。
|
||||||
|
//!
|
||||||
|
//! | 模块 | 职责 | 不负责 |
|
||||||
|
//! |---|---|---|
|
||||||
|
//! | [`theme`] | 令牌（`unlucky-design`）→ iced 类型：`Color` / `Font` / `Radius` / `Theme` | 发明令牌值 |
|
||||||
|
//! | `cli` | `--renderer` / `--software-renderer` / `--theme` / `--screenshot*` 参数 | 业务开关 |
|
||||||
|
//! | `probe` | 渲染后端探测（D27）+ 写 `ICED_BACKEND`，失败自动降级 CPU | 绘制 |
|
||||||
|
//! | `fonts` | 字体栈求值（D28 前半）：平台族名 → 系统字体库校验 → 启动日志 | 中文字体下载 |
|
||||||
|
//! | `app` / `shell` | Elm 三件套 + 自绘标题栏 / 导航轨 / 内容骨架 | 业务逻辑 |
|
||||||
|
//! | `shot` | `window::screenshot` → PNG（验收通道） | 图像比对 |
|
||||||
|
//! | `icons` | 令牌里的 SVG path → iced `svg` 控件 | 画新图标 |
|
||||||
|
//!
|
||||||
|
//! ## 消费纪律
|
||||||
|
//!
|
||||||
|
//! **组件层零硬编码色值/字号/半径/间距**：一律走 [`theme::Ui`]。守门测试在
|
||||||
|
//! `tests/no_hardcoded_tokens.rs`（扫 `src/**`，出现 `#RRGGBB` / `Color::from_rgb(` 即红）。
|

//!
|

|
//! ## 与 Slint 版的关系
|

|
//!
|

//! 并存期：`crates/app` 仍出 `unlucky-launcher`，本 crate 出 `unlucky-launcher-iced`。
|
||||||
|
//! 等价验收后翻牌（bin 改名 + 旧 crate 降级），步骤写在
|

//! 渲染后端探测 + 自动降级（D27）。
|
||||||
|
//!
|
||||||
|
//! ## 为什么需要探测
|
||||||
|
//!
|
||||||
|
//! iced 0.14 的 `Renderer` 本身就是「wgpu → tiny-skia」的运行时回退枚举（M60 Q1）：
|
||||||
|
//! **不设** `ICED_BACKEND` 时，拿不到 GPU 适配器会自动降级到 CPU，零代码。
|
||||||
|
//! 需要自研的只有**判据**：
|
||||||
|
//!
|
||||||
|
//! - 本机会枚举出 `Microsoft Basic Render Driver [Cpu]`（= WARP 软光栅），
|
||||||
|
//! 所以「有没有适配器」不能当「有没有 GPU」（M60 实测），必须看 `device_type`。
|
||||||
|
//! - 没有硬件 GPU 时要**主动**把 CPU 放到候选首位（`tiny-skia,wgpu`），
|
||||||
|
//! 否则 wgpu 会先花时间尝试 WARP，观感与行为都难料。
|
||||||
|
//!
|
||||||
|
//! ## 语义订正（与 M60 备忘录的差异，以源码 + 实测为准）
|
||||||
|
//!
|
||||||
|
//! M60 记「`ICED_BACKEND=wgpu` 会**关闭**回退」。读 `iced_renderer-0.14.0/src/fallback.rs`
|
||||||
|
//! 得到的是：**候选列表**语义——列表里没有 `tiny-skia` 时才真的关闭回退。
|
||||||
|
//! 所以本 crate 的「优先 GPU」写 `wgpu,tiny-skia`（首选 GPU，拿不到仍降级，**绝不硬失败**），
|
||||||
|
//! 而不是 `wgpu`。

//! 截图通道（D30 验收用）：`iced::window::screenshot` 的真窗口出图 → PNG，以及两图逐像素对比。
|

|
//!
|
||||||
|
//! ## 为什么用真窗口而不是 `iced_test::Emulator`
|
||||||
|
//!
|
||||||
|
//! 任务书首选路径①：真开窗截图覆盖了标题栏/DPI/窗口管理的真实行为，离屏通道不覆盖
|
||||||
|
//! （M60 §Q6 的边界说明）。本机与 Windows CI 都有交互会话，所以走路径①。
|
||||||
|
//!
|
||||||
|
//! ## 关键事实（M60 踩坑 Q3）
|
||||||
|
//!
|
||||||
|
//! `Screenshot` 的字节字段在 0.14 叫 **`rgba`**（0.13 是 `bytes`），`size` 是**物理像素**，
|
||||||
|
//! 另带 `scale_factor`（换算逻辑坐标用）。落盘用 `image::save_buffer` + `ExtendedColorType::Rgba8`。
|
||||||
|
//!
|
||||||
|
//! ## 为什么自己带一个 diff
|
||||||
|
//!
|
||||||
|
//! D30 的硬项是「GPU 档与 CPU 档**几何逐像素一致**，只有颜色/材质不同」。CI 里不该假设有
|
||||||
|
//! Python/PIL/ImageMagick，所以把「读两张 PNG → 数差异像素 → 给最大/平均通道差」做进本程序
|
||||||
|
//! （`--diff a.png b.png`），复用同一个二进制。

|

//!
|
||||||
|
//! ## 边界（M61 `design-令牌约定.md` §0 的落地）
|
||||||
|
//!
|
||||||
|
//! 本模块是**唯一**允许把 `unlucky-design` 的值翻成 iced 类型的地方。组件层（`shell`）
|
||||||
|
//! 只调 [`Ui`] 的方法，绝不出现色值 / 字号 / 半径 / 间距字面量——`tests/no_hardcoded_tokens.rs`
|
||||||
|
//! 会扫 `src/**` 做守门。
|
||||||
|
//!
|
||||||
|
//! ## 为什么不用 `iced::theme::Base` 自定义主题承载 49 个角色
|
||||||
|
//!
|
||||||
|
//! `iced` 的 `Palette` 只有 6 个颜色（`background/text/primary/success/warning/danger`），
|
||||||
|
//! M3 有 49 个角色，塞不进去（M60 Q5 + M61 §9-0 的同一结论）。所以：
|
||||||
|
//!
|
||||||
|
//! - **真源**是本模块持有的 [`Scheme`]（49 角色）；
|
||||||
|
//! - iced 的 `Theme` 只用来「换名字」——`Theme::name()` 变了 iced 才会重算受主题影响的缓存
|
||||||
|
//! （M61 §9 的最后一条）。`palette()` 只给 devtools 看，控件外观一律由各自的 `Style` 注入。
|
||||||
|
//!
|
||||||
|
//! `success` / `warning` 在 M3 里**没有对应角色**（`design-令牌约定.md` §2 明写），
|
||||||
|
//! 这里按「语义最近的现成角色」映射：`success → Secondary`（不是「成功」的承诺）、
|
||||||
|
//! `warning → Tertiary`（M3 把「提醒」放 Tertiary）。任何控件都不要去读这两个槽位。
