fix: resolve matrix rain opacity, menu styling, and featured articles

Issues fixed:
1. Added missing header.css and footer.css imports to main.css (fixes unstyled menu)
2. Increased matrix rain canvas opacity (0.13→0.25, 0.18→0.35) for better visibility
3. Updated home.html to display featured articles first, then latest 3
4. Removed invalid pseudo-element CSS rule on canvas element

The form on /is/here should now be visible, menu properly styled, and matrix rain more prominent.
