# 蛇足ですが…。
（1）ベースラインを揃えるのであれば、取得すべき高さは：
\settoheight{\myht}{着目}
のほうでした…。
（2）つい横着をして \llap を使ってしまいましたが、LaTeX 的には：
\makebox[0pt][r]{<text>}
としたほうがよかったのかも知れません。
【参考】TLC 3rd, Part II, 2023, p. 662:
[warning sign] Useful, but dangerous
There are also three useful but somewhat dangerous lower-level
commands you often find in package code: \llap, \clap, and \rlap.
.....
They inherit the behavior of the \hbox command; i.e., they do not
start a paragraph if used in vertical mode (which is sometimes
what you want), but more importantly they are not color safe unless
you add an extra pair of braces in their argument.
