Pixel Mouse Reporting (1016)
SGR-Pixels mouse mode (mode 1016) reports mouse coordinates in pixels rather than cells. This enables sub-cell precision for applications that need exact pointer positioning, such as terminal-based drawing tools or image viewers.

Enable SGR pixel mouse (
CSI ? 1016 h), check getMode("pixelMouse") returns true.The same probe runs against headless backends (via Termless) and real terminal apps (via a daemon launched in each terminal). This lets us distinguish parser correctness from rendering correctness.
