The Nintendo Game Boy (1989) was engineered around a deliberate limitation: a 160×144 dot-matrix LCD that could render only four shades of swampy green. Gunpei Yokoi's philosophy of "lateral thinking with withered technology" turned that constraint into a visual language, and Tetris, Pokémon, and Link's Awakening proved that whole worlds fit inside `#0F380F`–`#9BBC0F`.

This system treats those four greens as non-negotiable canvas, with a maroon `#8B1A30` accent lifted from the DMG-01's A/B buttons. Everything snaps to an 8×8 pixel grid, corners are hard, gradients are dithered, and type is pixel-native. The mood is constraint, craft, and cartridge-era optimism.
