Flashes the on-board LED as 3, 1, 4, 1, 5 with pauses between digits and a longer pause before repeating. The pattern is stepped from the hardware timer rather than blocking sleeps, so the USB serial port stays responsive and can reset the board back into BOOTSEL on request. Includes the original plain 250 ms blink under alt/ and prebuilt .uf2 images.
