Subject: [PATCH] fix: make landing page fully responsive for mobile devices
 (#3)

- Reduce hero/CTA text size on small screens via responsive clamp()
- Add max-w constraints to ambient glow elements to prevent overflow
- Tools grid: 1 col on smallest screens, 2 on xs, 4 on sm+
- Compact nav on mobile: reduced padding, smaller text, shorter height
- Responsive section padding throughout (px-4 on mobile, sm:px-6)
- Footer: stack vertically on mobile, center text
- Hide secondary glow on mobile (hidden sm:block)
