Thanks for the PR. Unfortunately, this is semantically incorrect. An <a> element cannot be a descendant of another <a> element. If we want to make this change, the card structure needs to be reworked. The card should contain two separate links, and for the CSS, we could potentially use the :has() selector to highlight the card. Additionally, we need to ensure that clicking on the GitHub link does not trigger the main call-to-action.

Side note: For the icons we can use svg.
