No, it isn't. You're confusing the wrapper with the contents.

alignof(c) is 8 because it has a pointer and a 64-bit type. Though you should
have written with size_t or ssize_t, and thus the alignment would be
alignof(void*).

alignof(c.data()) is 1, because the payload is a char array.

None are going to be 3. That's not a valid alignment value anywhere
(alignments are always a power of 2).
