New hero section:

• Animated typing demo that cycles through real examples showing voice-to-text in action (spoken input → clean typed output)
• Floating glow orbs with parallax orbital dots
• Gradient text, subtle grid background
• Progress bar showing typing state

New effects:

• Scroll-triggered reveal animations on every section
• Animated stat counters (50+ languages, 3 modes, 40+ commands, $0)
• Gradient border cards with hover accent lines
• Intersection Observer for performance

Restructured layout:

• Stats bar after hero for immediate impact
• "How it works" with numbered cards and hover effects
• Live demo section (real Web Speech API) as standalone section
• Features grid with accent colors and divider lines
• Competitor table with checkmarks/dashes, gradient border
• CTA section with animated underline hovers
• Refined footer
