    A HiF4 Matrix scale MUST be one raw U32 word containing E6M2 in bits 7:0, eight E1_8 exponents in bits 15:8, and sixteen E1_16 exponents in bits 31:16. E6M2 values 00..FE MUST be finite with bias 48 and two fraction bits; FF MUST be a legal quiet NaN scale. One word scales 64 logical HiF4 lanes through the selected E1_8 plus E1_16 exponent bits.
