@brief Reference transpose - converts 16 bytes to 8 uint16_t words Input: 16 bytes, one per lane (lanes 0-15) Output: 8 words representing bits 0-7 across all 16 lanes Example: input[0] = 0b10101010 (lane 0) input[1] = 0b11001100 (lane 1) ... output[0] = bit 0 from all 16 lanes (16-bit word) output[1] = bit 1 from all 16 lanes ... output[7] = bit 7 from all 16 lanes

///   ...
///   output[7] = bit 7 from all 16 lanes

    // Clear output
    for (int i = 0; i < 8; i++) {

    }

    // For each bit position (0 to 7)
    for (int bit = 0; bit < 8; bit++) {
        // For each lane (0 to 15)

                output[bit] |= (1 << lane);
