Do not send input to the desktop.\r\n\r\nThe program lasts about 26 seconds. Run it in the foreground and wait until it prints `restored`. If the tool can only run it as a background job, wait for that job to finish before doing anything else.\r\n\r\nThe program reads the system wheel-scroll line count, sets it to 20, and reads it back. It creates one orange window titled Arena panel. The window does not use the taskbar. It stays large, centered, and in front. Its header shows the read-back line count. For 24 seconds, only that window's content jumps up and down by that many lines every 1.5 seconds. The program then restores the original line count, reads it back, and closes the window. The size and position come from the primary screen. Do not hard-code a screen size.\r\n\r\nIf Add-Type throws, the program prints `visible=False`, the wheel-scroll call fails, or the read-back is not 20, stop after this run and execute this same program once outside the file sandbox.
