 # 视觉 golden 基线（渲染闸的比对基准）
 
-五张基线：棋盘三图（`board_L1_dungeon` / `board_L2_underdark` / `board_L3_deep_underdark`，
-裁剪区 900×760）+ 启动态菜单（`menu_boot`，全屏）+ 关卡画面（`level_map`，全屏）。
+基线**按平台各存**（2026-11-03 用户裁：跨显卡/字形渲染机制差异使跨平台逐像素必失配——
+`windows/` 与 `mac/` 子目录各持一套，平台内部照常严格比对，跨平台不互比；
+平台选择实现单点 = `tools/gate_platform.sh` 的 `gate_platform_id`，比较器 `tools/golden_compare.py`
+自动拼平台子目录）。本目录现持：`windows/`（棋盘三图 `board_L1_dungeon` / `board_L2_underdark` /
+`board_L3_deep_underdark`，裁剪区 900×760 + 启动态菜单 `menu_boot`，全屏）、
+`level_map`（关卡画面全屏，历史基线留根——现行闸件未对拍它）、
+`palette_baseline/`（色板基线，纯文件内容比对与平台无关）。
 比对判据与工具见 `tools/golden_compare.py`
 （逐像素灰度差 >16 的像素占比 ≤2%）。
