+//! 滚动截图（垂直长图拼接）底层设施（仅 Windows）
+//!
+//! ## 原理
+//! 目标窗口的**客户区**内容往往是可分页垂直滚动的。算法：
+//! 1. 用 PrintWindow（PW_RENDERFULLCONTENT）抓客户区为 BGRA（不做 PNG 编码）；
+//! 2. 向窗口发送 `WM_MOUSEWHEEL` 使其向下滚动；
+//! 3. 再抓一帧，用**框选带内多列采样行信号**做一维模板匹配，求出两帧间的垂直
+//!    滚动像素偏移 `d`：`cur[y] ≈ prev[y+d]`，故把 `cur` 底部新出现的 `d` 行拼到画布末尾；
+//! 4. 重复直到内容不再变化（滚到底部），把各帧拼成一张超高纵轴图像。
+//!
+//! 固定表头/粘性头部由拼接语义天然处理——只追加 `cur` 底部的 `d` 行，
+//! 表头保留在第一帧中，不会重复。
+//!
+//! ## 滚轮投递
+//! `WM_MOUSEWHEEL` 优先发给**框选带中心处的最深子窗口**（如 Chromium 的
+//! RenderWidgetHostHWND）：很多程序的顶层窗口过程不转发滚轮消息，
+//! 直接发顶层会导致"完全不滚动"。坐标一律用屏幕物理坐标（lParam 语义）。

+//!
+//! 与 [super::scroll_capture::scroll_capture]（同步一次调用）不同，本模块把捕获循环
+//! 放进后台线程，通过事件把**实时进度**推给前端。
+//!
+//! ## 自动模式架构
+//! - **run_loop（会话线程）**：按节奏捕获客户区帧，与上一帧做带内偏移匹配，拼接新行；
+//! - **ticker（滚轮线程）**：以 ~16ms 间隔发送小步长 `WM_MOUSEWHEEL`，由目标程序自身的
+//!   平滑滚动动画呈现连续滚动（替代旧版"每 70ms 一整格"的跳变式滚动）；
+//! - **目标策略升级**：带中心最深子窗口（小步长 Send）→ 子窗口整格 → 顶层整格 Send →
+//!   顶层整格 Post。解决"一开始就不滚动"（顶层不转发滚轮 / 程序忽略非整格消息）；
+//! - **自适应速度**：按每周期实测位移调滚轮步长 / 捕获周期，逼近"带高 1/4"的理想重叠；
+//! - **停止补帧（settle）**：用户停止后等目标窗口滚动动画静止再补拼最后一帧，
+//!   保证最终图片结尾 = 用户停止时窗口实际停留的位置；
+//! - **精准回滚**：先按累计像素粗估上滚，再用帧匹配对初始帧校准回到起始位置。
+//!
+//! 事件（广播到所有窗口）：
+//! - `SCROLL_PROGRESS`：`{ width, height, auto }` 当前已拼接高度
+//! - `SCROLL_COMPLETE`：`{ width, height }` 完成导出（PNG 原始字节已存入编辑器图片槽，
+//!   由前端常驻编辑器窗口通过 raw IPC 取出，事件本身不携带图片数据）
+//! - `SCROLL_CANCELLED`：`{}` 取消（丢弃画布）

+//! HDR 全屏捕获实现（Windows Graphics Capture + HDR→sRGB 色调映射）
+//!
+//! ## 为什么需要它
+//! Windows 高级色彩（HDR）开启时，桌面由 DWM 用**线性 scRGB（RGBA16F）**合成。
+//! [crate::screenshot::capture] 的 `BitBlt` 从屏幕 DC 直接取出 8bit 像素，
+//! 把这些线性/scRGB 高亮值当 sRGB 编码，会导致亮部越界被裁、局部过曝失真。
+//!
+//! ## 方案
+//! 检测到任意显示器为 HDR 输出时，改用 WGC：
+//! 1. 以 `RGBA16F`（scRGB 线性）捕获每个显示器；
+//! 2. 按 SDR 参考白缩放（`÷ (sdr_white_nits / 80)`）后钳制到 [0,1]；
+//! 3. 做 sRGB 伽马编码，得到与屏幕观感一致的 BGRA8；
+//! 4. 按各显示器在虚拟屏上的偏移拼接到一整张虚拟屏图像（与 BitBlt 输出同构）。
+//!
+//! 仅当 HDR 时才走此路径；SDR 显示器仍用快速的 BitBlt。
