-// SB64 is useful for B64 map keys. Idiomatically, map key type should be `B64`,
-// but currently in Go map keys are only type `string`, not `[]byte`.  Since
-// B64's underlying type is `[]byte` it cannot be used as a map key. See
-// https://github.com/golang/go/issues/283 and
-// https://github.com/google/go-cmp/issues/67.  SB64 will be deprecated if/when
-// Go supports []byte keys.
-//
-// This is an acceptable hack because (from https://go.dev/blog/strings)
-//
-//	>[A] string holds arbitrary bytes. It is not required to hold Unicode text,
-//	> UTF-8 text, or any other predefined format. As far as the content of a
-//	> string is concerned, it is exactly equivalent to a slice of bytes.
