Grau Zero

This reconstruction separates Grau Zero from the combined 1985 exhibition selector while preserving its own title sequence, randomly selected scale and rotation, and the 256-position XDRAW progression of shape 2.

The original 21-byte Apple II speaker routine is recreated with Web Audio. The descending pitch parameter and drawing progression were recalibrated against the three-run Virtual ][ recording; browser sound remains a representative reconstruction rather than a cycle-exact emulation of the Apple IIe speaker.
