//! 设置页「Appearance」分组文案（M116 落了圆角一族；M180 `I18NAPPEAR` 补齐全组）。
//!
//! 加 key 时把条目写进 `$($acc)*` 后面即可（形状见 [`crate::catalog`] 的「域装配」一节）。
//!
//! ## 两批 key：圆角（M116）在前，其余（M180）在后
//!
//! M116 只落了圆角那 5 条；本分组其余控件（整窗/面板透明度、背景图、填充、暗化、配色来源）
//! 是 M93 落的，文案一直是英文基线字面量。M172 审计量出这一页 27 处文案里 22 处硬编码、中文界面
//! 本地化 0/27。M180 把**控件文案 + 运行时诊断 + 配色回落提示**全部搬进本文件：
//!
//! | 批次 | 条目 | 来源 |
//! |---|---|---|
//! | M116 | `Corner` … `CornerSuspended` | `pages/appearance/section/window.rs` 的圆角一段 |
//! | M180 | `WindowOpacity` … `PaletteAdjusted` | 卡片各段标签/说明 + `state.rs` / `background.rs` / `palette.rs` 的诊断 prose |
//!
//! ## 为什么诊断也在这里（而不是留在 `state.rs`）
//!
//! `pages/appearance/state.rs` 已经 390 行、贴着 400 行硬线，放不下任何一张文案表。所以那一层只
//! 给 **key + 已格式化好的参数**（`background::Note`），句子一律在本文件里。
//!
//! ## 数值参数：模板里只有 `{name}`，格式在 Rust 侧做
//!
//! [`crate::catalog::Catalog::render`] 只做 `{name}` → 值的字面替换，**不认** `{:.2}` 这类格式说明。
//! 所以「位置/尺寸/上限」这些数字由调用方先 `format!("{:.2}")` 好再当参数传进来：
//!
//! | key | 原字面量 | 现在 |
//! |---|---|---|
//! | `SettingsAppearancePanelOpacityForcedValue` | `format!("100% (forced from {:.2})")` | `{requested}` = `format!("{:.2}")` |
//! | `SettingsAppearanceWindowOpacityHint` | `Floor {:.2}` = `WINDOW_ALPHA_FLOOR` | `{floor}` |
//! | `SettingsAppearancePanelOpacityHint` | `Floor 0.40` = `PANEL_ALPHA_FLOOR` | `{floor}` |
//! | `SettingsAppearanceBgDimHint` | `Max 0.95` = `BG_DIM_MAX` | `{max}` |
//! | `SettingsAppearanceBgTooLarge` | `(limit 8192 px per edge)` = `MAX_SOURCE_EDGE` | `{limit}` |
//! | `SettingsAppearanceBgSmallTile` | `(max 64 tiles …)` = `MAX_TILES` | `{max}` |
//!
//! 常量走占位符而不是写进译文，是为了「改常量不用改两套译文」（M180 任务口径）。
//!
//! ## 文案口径（不许暗示所有平台一致）
//!
//! 用户定案：Win11 / Server 2025 开系统圆角，Win10 可以不开，其他系统按窗口合成器的默认规则。
//! 所以说明句必须写清「谁负责画圆」而不是「我们支持圆角」——后半句在 Win10 上是假的。
