Suggest also adding a white border as the background would not stand much vs the sidebar background color.

background-color: var(--atum-bg-dark-60);
border: 1px solid white;

which would give

instead of this with this pr

Not required for accessibility. That's a styling change which is beyond the scope of this pr and should be considered as a separate issue as it would impact the consistency of badge styling elsewhere

I doubt about that. main-nav is only used by the admin mod_menu.

css is in _sidebar.scss

// Sidebar navigation
.main-nav {

[...]

.badge {
    align-self: center;
    margin: 0 .3rem .25rem;
    background-color: var(--atum-bg-dark-50);
  }

Just say you don't want to do the change in a a11y PR. That's enough.

I meant consistency with badges everywhere not just sidebar.

Maybe out of topic, but why duplicate language tag?

It is not a duplicate. The tag added to the menu title comes from the multilingual sample data and it is there on purpose.
On a real site it is not necessary.

Thanks!
