This isn't a full fix for perfect responsiveness on mobile (so I'll keep the issue open). But this addresses the critical issues. There's still one specific zoom + window width combination where this happens (notice the images not completely covering and the double scrollbar)

Fixes:

• leaked anchor CSS with !Important
• Reduced a layer of div inside anchor
• Fixed squished images
• Fixed completely broken Card display in mobile view
