- Add grid-cols-1 explicitly for mobile to ensure single column layout
- Add overflow-x-hidden to .main-content to contain horizontal overflow
- Add overflow-hidden to .sidebar and .widget components
- Add overflow-x-hidden to .e-content and .prose containers
- Add overflow-hidden to .post-card for containing wide content
