Modern Minimalist Chat Inbox

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 message inbox with a search bar, a horizontal row of story-style avatars, and a list of conversation rows each with avatar, name, message preview, time and an unread count badge.

Visual style — Modern Minimalist:
Typography carries the hierarchy through opacity levels of a single near-black ink rather than through different colors. Cards sit on the background with almost invisible 1px borders and a very soft shadow. Corner radii: cards 16px, buttons 20px, search bar 28px. Simple outline icons with 2px stroke. Generous whitespace and Apple-inspired spacing. Flat — no gradients, no glass. Calm, premium, elegant and highly readable.

Color palette — Warm Sage:
Warm off-white #FCFBF8 background, white cards. Ink #14181A at 100% / 70% / 44%. Borders rgba(20,24,26,0.10). Accent muted sage green #4F7A5C.

Typography — use these exact font families:
- Headings / display: -apple-system, BlinkMacSystemFont, "SF Pro Display", "Segoe UI", sans-serif
- Body / labels: -apple-system, BlinkMacSystemFont, "SF Pro Text", "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).
