// Unlucky-Launcher · 主入口窗口（P0 阶段 B 接线）
//
// 布局真相源：DevDocs/PlanDoc/09-ui-layout.md（D16：左侧固定导航 + 右侧 AI 常驻栏 + 磁贴实例页）。
// 本文件只做三件事：①无边框窗口与字体/缩放口径 ②实例化 `AppShell` ③把 AppShell 的全部
// 属性/回调原样上抛给 src/main.rs（Slint 只能从根组件访问属性与回调，所以这层转发是必需的）。
//
// 与 M11 骨架的关系：M11 的 `Metro` palette global（accent/surface/sidebar/tile/text/muted/pad/gap）
// 已由 `theme/tokens.slint` 的 `Theme` 继承并扩展——同一「palette global 令牌化」思路，但多了
// 亮/暗双套色板（LightPalette/DarkPalette）、主题三态解析、排版 ramp 与字体栈；M11 的占位
// NavItem/Tile 组件由 `components/nav.slint` 与 `components/tile.slint` 取代，占位内核不再保留。

// P3：页面状态 global 从根文件再导出一遍，Rust 侧才能拿到 `PageState` 类型。
