Subject: [PATCH] fix: make landing page responsive for mobile devices (fixes
 #3)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds responsive breakpoints throughout LandingPage.tsx:
- Nav: responsive padding (px-4 sm:px-6) + gap adjustments
- Hero: responsive text sizes (text-3xl sm:text-4xl md:text-5xl)
- Prism: clamp() for fluid sizing (200px-340px based on viewport)
- Ambient glow: clamp() for fluid sizing
- Tools grid: 2 cols on mobile → 3 on tablet → 4 on desktop
- Steps grid: 1 col on mobile → 3 on desktop
- Section padding: reduced on mobile (px-4/py-12) vs desktop (px-6/py-20)
- Footer: responsive padding

Uses Tailwind CSS responsive prefixes + CSS clamp() for fluid sizing.
No new dependencies. Backward compatible (desktop layout unchanged).
