+ORB Feature Matching (Rotation / Scale / Theme Robust)
+======================================================
+
+Pixel template matching — ``match_template``, ``match_masked`` — correlates the
+template's pixels against the screen, so it breaks the moment the target is
+*rotated*, scaled by a factor you did not list, or re-coloured (a light-vs-dark
+theme, a hover state, a different skin). ``feature_match`` instead matches
+*keypoints*: distinctive corners described by orientation-invariant binary
+descriptors (ORB), then fits a RANSAC homography through the consistent ones. It
+locates the element under rotation, scale and appearance change, and reports the
+four projected corners plus the inlier count as a built-in confidence signal.
+
+It runs on an injectable ``haystack`` image (ndarray / path / PIL), so it is
+unit-testable on synthetic arrays without a real screen. ORB, the brute-force
+matcher and ``findHomography`` are all in core OpenCV (no contrib modules);
+OpenCV + NumPy come in via ``je_open_cv``. Imports no ``PySide6``.
+
+Headless API
+------------
+
+.. code-block:: python
+
+    from je_auto_control import feature_match
+
+    hit = feature_match("logo.png", min_inliers=12)
+    if hit:
+        click(*hit.center)            # centre of the located quad
+        print(hit.corners)            # 4 [x, y] points, in template order
+        print(hit.inliers, hit.score) # geometric inliers and inlier fraction
+
+``feature_match`` returns a ``FeatureMatch`` (``corners``, ``center``,
+``inliers``, ``matches``, ``score``) or ``None`` when fewer than ``min_inliers``
+geometrically consistent matches survive. ``ratio`` is Lowe's ratio-test cutoff
+(lower = stricter); ``max_features`` caps the ORB keypoint budget. The ORB border
+and patch sizes are scaled down automatically for icon-sized templates, which
+OpenCV's defaults would otherwise reject outright.
+
+Executor command
+----------------
+
+``AC_feature_match`` takes ``template`` plus ``region`` / ``max_features`` /
+``ratio`` / ``min_inliers`` and returns ``{found, match}``. It is exposed as the
+MCP tool ``ac_feature_match`` and as a Script Builder command under **Image**.

+ORB 特徵比對(對旋轉 / 縮放 / 主題穩健)
+========================================
+
+像素模板比對——``match_template``、``match_masked``——是把模板像素與螢幕做相關運算,因此目標一旦*旋轉*、
+以未列出的倍率縮放、或重新上色(亮 / 暗主題、hover 狀態、不同外觀),就會失效。``feature_match`` 改為比對
+*關鍵點*:以方向不變的二進位描述子(ORB)描述的特徵角點,再用 RANSAC 對一致的點擬合單應矩陣。它能在
+旋轉、縮放與外觀變化下定位元素,並回傳四個投影角點以及做為內建信心訊號的內點數。
+
+它在可注入的 ``haystack`` 影像(ndarray / 路徑 / PIL)上執行,因此可在無真實螢幕下對合成陣列做單元測試。
+ORB、暴力比對器與 ``findHomography`` 皆屬於 OpenCV 核心(不需 contrib 模組);OpenCV + NumPy 透過
+``je_open_cv`` 引入。不匯入 ``PySide6``。
+
+無頭 API
+--------
+
+.. code-block:: python
+
+    from je_auto_control import feature_match
+
+    hit = feature_match("logo.png", min_inliers=12)
+    if hit:
+        click(*hit.center)            # 定位四邊形的中心
+        print(hit.corners)            # 4 個 [x, y] 點,依模板順序
+        print(hit.inliers, hit.score) # 幾何內點數與內點比例
+
+``feature_match`` 回傳 ``FeatureMatch``(``corners``、``center``、``inliers``、``matches``、``score``),
+或在幾何一致的比對少於 ``min_inliers`` 時回傳 ``None``。``ratio`` 是 Lowe 比例測試的門檻(越低越嚴格);
+``max_features`` 限制 ORB 關鍵點預算。ORB 的邊界與 patch 尺寸會針對圖示大小的模板自動縮小,否則 OpenCV
+的預設值會將其全數捨棄。
+
+執行器命令
+----------
+
+``AC_feature_match`` 接受 ``template`` 以及 ``region`` / ``max_features`` / ``ratio`` / ``min_inliers``,
+回傳 ``{found, match}``。它以 MCP 工具 ``ac_feature_match`` 以及 Script Builder 中 **Image** 分類下的命令提供。
