I've not made a mistake. I've not mixed up bits and bytes. Please show me a quote where that happened?

I don't know why you are trying to gaslight.

If you don't know how CPU's work just say you don't know how it works!
That's fine.

I won't be wasting my time trying to explain in circles why alignment matters.
I'm not a library! There's the internet, go look for the material yourself.

Now you are just trying to justify your mistakes after the fact. In
another reply, you said you had mixed up bits and bytes.

If you want to over-align an object, beyond the requirements of the
platform and ABI (for cache friendly data, or any other purpose), use
"alignas" just as you always do.
