Detailed Description

The useful part of simd cells is in luminance: together they describe what is pending, who owns it, and how much data is valid. Keep the object with its parent operation and use the parent cleanup path. Row callbacks read/write exactly count elements. Glyph correlation reads 16 samples. Only short row tails use scalar code.

SIMD stages operate on complete rows of host-order packed RGB and UTF-8 keys.
