Major upgrade: next-level UX for both pages

try.html — New features:
- Radar/spider chart for theory score visualization (pure SVG)
- Animated count-up transitions on all scores
- Consciousness spectrum bar (gradient red→green with marker)
- Gauge particle effects (canvas-based orbiting particles)
- Share results via URL (base64 encoded, clipboard copy with toast)
- localStorage audit history (persists across sessions, 50 entries)
- Session comparison table (side-by-side after 2+ audits)
- Mini leaderboard from past audits (ranked by best score)
- Enhanced indicator cards (color-coded progress bars, theory tags, hover effects)
- Smooth scroll to results on completion
- Fade-in animations with staggered delays

index.html — Full landing page overhaul:
- Hero section contained (scrollable page below)
- "or try instant demo" link below ENTER
- 7 new content sections with scroll-reveal animations:
  1. "What is Chetana?" — 3 feature cards
  2. "How It Works" — 3-step visual flow
  3. "Sample Audit Results" — interactive preview
  4. "Model Leaderboard" — top 5 models
  5. "Six Theories of Consciousness" — 6 theory cards
  6. "The Science" — Butlin et al. quote + stats
  7. "Ready to Test?" — final CTA
- Footer with links
- IntersectionObserver scroll-reveal with child stagger
- Responsive mobile layout
