nostr:nprofile1qqsyvrp9u6p0mfur9dfdru3d853tx9mdjuhkphxuxgfwmryja7zsvhqelpt5w some fixes:
1. You can add this to code injections to fix the banner position on mobile:
<style>
img.gh-header-image {
    object-position: left;
}
</style>
2. Could you please go to Theme settings and re-publish the site? This should fix the Github/Obtainium icons on mobile, and should make the image appear on your mascot post page.
