Card narrow on large screens, width cannot widen

[hungryalgo]

I am using the example from tabs, with cards in the tabs:
https://www.shadcn-svelte.com/docs/components/tabs

The cards always appear very narrow, the same width as when in mobile, even when using large screens. I cannot change the width of the cards at all.

Is there a way to change the width of a card, when on large screens e.g. desktop?

I tried a bunch of things, but none worked, e.g.:
style="max-width: 48rem;" on card, also tried that on tabs.
