Summary

This PR includes two related UI improvements:

---

1. Fix: Mobile sidebar overflow (Issue #1949)

On screens below 1024px, opening the sidebar caused the page to become wider than the viewport — triggering horizontal scrolling and shifting the layout.

The fix ensures:

• Sidebar stays within viewport width
• No horizontal overflow on open/close
• Main content remains stable
• Correct overflow-x-hidden and layout constraints applied

---

2. UI improvement: Simplified homepage email and link styling

The “Email us” link on the homepage previously looked inconsistent with other links and required hover to appear interactive.

Updated styling:

• Uses standard underline styling
• Adds a hover effect
• Cleaner and more consistent across breakpoints
• No layout shift, works better on small screens

This improves clarity and accessibility without major design changes.
