Shorten RGB-split bands to 4px max, per request

GLITCH_STATE_POOL's height values were 10-13px (sized to reliably show
2-3 scanlines within a band); capped to 2-4px thin slivers instead. No
longer tall enough to guarantee scanline overlap, which is fine -- the
shorter height was the explicit ask.

Verified 0 black-corner hits across 228 frames, payload 291KB (down
from 320KB with the taller bands).
