//! 组件档位数据表（**下标必须等于 `Component as usize`**，由测试钉死）。
//!
//! 一行一个组件。改值就是在改全站观感——同步协作文档再改。
//!
//! **末尾 5 行（M69 G9）** 的来源是 `research/15` §18~§23（同一套 `material3-android:1.4.0` 源码）：
//! Checkbox / Radio / Search / NavigationDrawer / Divider。其中 Checkbox 的 **2dp** 圆角走
//! [`ComponentRadius`]（D32 第二层，不塞进 `ShapeScale`），Divider 的厚度是一像素线（G12）而不在这张表里。
//!
//! **高程/形状取值来源（A 级）**：`androidx.compose.material3.tokens` 的各组件 `<X>Tokens.kt`
//! （FilledCard/OutlinedCard/ElevatedCard/Menu/Dialog/Snackbar/AppBar/List）。已登记的两处偏离：
//! - `Tooltip`：`PlainTooltipTokens.kt` 只有 Corner 行、**没有 Elevation 行**，Table 的 Level2 是
//!   B 级（沿用 M3 旧规范「浮层 3dp」的直觉），有官方值后以官方为准；
//! - `ListItem`：官方 `ListTokens` 用 `CornerNone`（直角行），本项目取 `Small(8)`——列表行在本
//!   启动器里是**卡片内的独立可点块**（不是贴边通栏行），圆角与卡片同族更协调；偏差 8dp 已登记。
