The set was one fixed window with content sliding behind it. Now every room is its own framed puddle and carries its frame WITH it, so a drag pulls the whole web across the grid — an infinite lattice of little screens, wall between them, panning as one. On a diagonal you pull four framed puddles at once. Two asks fell out of the same change: - NEVER BLACK. The wall, the stage underlay, and the peek frames all take a slate tone now, never pure black — and it still contrasts the pad so the touchable area stays visible. - ALWAYS AN EDGE LINE. A lit RIM is baked into each puddle's frame, hugging the rounded boundary, so there's a visible line on every side no matter what the pad or the wall are doing. The frame overlay is glass-sized (rides with its room) instead of screen-sized (fixed), baked per wall colour and cached. Cell pitch is a full screen, so neighbors sit a wall's-width apart. Stress: voices bounded, heap ok, no errors. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
