Comic Book Chat Conversation

Act like a frontend developer with 15 years of experience. I want the exact same UI with 95-99% similarity.

Platform: This is a RESPONSIVE design — it should work on both mobile and desktop. Use mobile layout patterns (bottom nav, stacked content) for mobile, and desktop layout patterns (sidebar/nav bar, wider content areas) for web.

Design a chat screen with a header showing avatar, name and online status, alternating incoming and outgoing message bubbles with timestamps, and a rounded input bar with an attach icon and a send button.

Visual style — Comic Book:
Bold black outlines on every shape, halftone-dot shading in accent areas, speech-bubble-shaped callouts, and dynamic diagonal action-line motifs behind headers. Comic-style bold italic display font. Punchy, graphic-novel energy.

Color palette — Primary Comic:
Background #FFF9E8. Blocks red #E5303B, yellow #FFD23F, blue #2E5EAA. Outlines black #000000.

Typography — use these exact font families:
- Headings / display: "Arial Black", "Impact", sans-serif
- Body / labels: -apple-system, BlinkMacSystemFont, "Segoe UI", sans-serif

Commit fully to this style — it should be unmistakable at a glance. Use realistic content, not placeholder text. Keep animations smooth (200ms ease-out).
