Reset pointer fg color (OSC 113)
ESC ] 113 BELOSC 113 resets the mouse pointer foreground color to the terminal's configured default. The sequence is
ESC ] 113 BEL. This is the companion reset for OSC 13, which sets the pointer foreground color. The pointer color set originated in xterm to allow applications to customize the mouse cursor when hovering over the terminal — historically useful on X11 where the X cursor was not styled by the GUI toolkit. Support is mostly limited to xterm and a small number of xterm-compatible terminals that implement the full color management protocol.How this is testedpartial

OSC 113 BEL and verify the terminal remains responsive (sequence consumed without error).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.
