256×224. Plasma Layer (procedural sines), tile layer (32×28 at $E000), text layer ($F000), 32 sprites (defs at $FE00: shape<<8|colour), per-scanline wobble, palette cycling, mosaic, plus a built-in HUD counter because the engineers wanted to go home early.
8 channels, 8-bit @ 22 kHz, per-channel pitch ($FF10+ch, 256 = 1.0×), Grit bitcrusher. Samples: 0 KICK · 1 SNARE · 2 HAT · 3 AAH · 4 LASER · 5 BASS · 6 SHOUT · 7 COIN.

Cycle-based: 262 scanlines/frame, each visible line is rendered from live VRAM/IO after the CPU's per-line cycle budget. WAIT_VBL stalls until line 224. The BIOS is real K-16 code at $D000 that draws the boot screen, then JMPs to $0000.

8 families × 8 shades: Ember, Brine, Moss, Dusk, Coral, Static, Gold, Void. Index = family×8 + shade.
