feat: Add HTML/CSS random ChitChat landing page

[Copilot]

Bootstrap a static single-page site for a random stranger chat product from an otherwise empty repo.

index.html

• Nav — sticky glassmorphism bar with logo, anchor links, and primary CTA
• Hero — gradient headline, live-count badge, dual CTAs, four key stats
• Features — 6-card grid covering anonymity, matching speed, global reach, safety, and interest filtering
• Chat preview — functional interactive demo: send messages, simulated stranger replies with typing indicator, skip to new match
• How It Works — 4-step numbered cards
• CTA + Footer — conversion section and full footer with link columns
• Start Chat modal — interest-tag picker that feeds into the demo match simulation

style.css

• Dark theme via CSS custom properties (purple/pink gradient palette)
• Animated background blobs using filter: blur + @keyframes
• Glassmorphism header via backdrop-filter: blur
• Responsive via CSS Grid / Flexbox with breakpoints at 768 px and 480 px
• Typing indicator (translateY keyframe), card hover lifts, modal entrance transition

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
