"i cannot see the mouse on the mirror and cannot click on buttons on the mirror. unless i use the mouse i can't see."

⚠⚡ mss.grab() does not capture the cursor

That's true of mss on every platform, so the mirror has never once shown a pointer. Tapping moved a cursor nobody could find, which makes aiming at a button guesswork. The mirror was not missing click support — it was missing the ability to aim.

The pointer is now drawn onto each captured frame from pyautogui.position(), which is the same coordinate space the existing click mapping already uses, so what you see is exactly where a tap will land. Proved rather than assumed: the test maps the drawn arrow back through the client's own tap formula at four positions, including both corners.

• ⚠ Drawn black inside a white halo, not one flat colour. This is looked at on an e-ink reader, where a white arrow vanishes on a light window and a black one vanishes on a dark one. Asserted against both backgrounds.
• ⚠ Scaled with the frame. Frames are downscaled to ~1680px for the wire, so a true-size cursor would be a handful of pixels on a 6-inch screen.
• ⚠ It can never break the mirror. If the pointer cannot be read — no display, pyautogui unavailable — the frame is returned untouched. A failure costs the cursor, not the screen. Pinned by a test that makes position() throw.

Immediate feedback on tap

The drawn pointer only arrives with the next frame, which is a few hundred ms away and longer on the "Lite" speed — so until then a tap still produced nothing visible. A mark now appears where you touched.

⚠ A static mark that appears once and disappears once, not an animated ripple: on e-ink every frame of an animation is a full panel repaint, and the ripple would cost more flashes than the mirror itself.

The hint under the mirror said "Tap the mirror to click", which was true and useless without a visible pointer. It now says the arrow shows where the mouse is.

Tests

test_mirror_cursor.py (13): position accuracy at four points, off-screen and zero-size ignored, a throwing position() leaving the frame untouched, and legibility on both a white and a dark window.

⚠ The page's inline JS is syntax-checked separately — ast.parse on the Python file proves nothing about a string that happens to contain a script.
