Figma Social Network UI Design

I need a full-fidelity Figma design for a social-interaction platform built around three pillars: real-time messaging, rich user profiles, and a dynamic news feed. The look should be modern and sleek—clean lines, clear hierarchy, subtle motion, and a palette that works equally well in light and dark mode.

Scope
• Responsive web layouts for desktop and mobile breakpoints
• Key screens: onboarding, profile creation/edit, home feed, two-pane chat, notifications, search, and settings
• Component-based design system with tokens for color, type, spacing, and states
• Clickable prototype that walks a user through sign-up → feed → open chat → send message → view profile
• 1–2 micro-interaction samples inside Figma (e.g., message send or like animation)

Technical notes
Auto-layout, nested components, and logical layer naming are a must so developers can hand-off quickly. Please keep the file tidy and documented.

Acceptance criteria
1. Every listed screen present in hi-fi quality
2. Prototype paths function without dead ends
3. Reusable component library and style guide included
