At rest it's the baseline pixel <span className="k">S</span>. The <span className="k">Snake</span> trick dissolves
the letter into a single segment that slithers across the 5×5 board — a nod to the LAN-party era — then re-lays
itself back into the S. <span className="k">RGB datamosh</span> and <span className="k">Signal glitch</span> are
shorter flickers for a quicker hit. Both the big mark and the one in the top bar are the same live component.
