Section headlines are written out behind a column of digits, mono labels resolve from binary, the portrait assembles itself from bits, section indexes rattle and keep one bit alive, cards get corner marks, the header shows the scroll position as an eight-bit number, pressed links and buttons shed a few digits, and the work stage leans towards the pointer. All effects respect reduced motion and leave the content readable without JavaScript. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
