As I announced here: <https://protesilaos.com/news/2026-04-21-omitting-the-surname/>.

Thanks to Morten Kjeldgaard for bringing the matter to my attention in
issue 44: <https://github.com/protesilaos/ef-themes/issues/44>.

This is because the colours they use are not thematically consistent.
I realised this after seeing the Info interface that aikrahguzar
showed me in issue 70: <https://github.com/protesilaos/ef-themes/issues/70>.

We used to have those and I thought they were back in after the
redesign on top of Modus. But I never did that until the latest
commits to modus-themes.git.

This:

    commit a472f546459a80f3c95255118831d35a6dcbddf0

    Date:   Sat Nov 22 16:47:08 2025 +0200

      Update modus-themes-define-derivative-command-known-suffixes to include select-{dark,light}

And this:

    commit c270cd8f5ea431534b5e9d6455239d890d9ed055
    Author: Protesilaos Stavrou <info@protesilaos.com>

      Implement convenience commands modus-themes-select-{dark,light}

We now rely on the user options are commands that the modus-themes
define. What we provide here is for backward compatibility.
