StylusCheck Separates the Pen, the Screen, and the Software

Why it surfaced

StylusCheck turns a frustrating hardware mystery into a sequence of concrete tests, including live pressure readings, tilt and button checks, dead-zone mapping, and hands-off phantom-touch logging. It also states its limits plainly: raw values appear beside each PASS/WARN/FAIL verdict, and drawings or typed input stay on the device.
