Tropical Vibrant 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 — Tropical Vibrant:
Large leaf and palm-frond silhouette motifs as decorative background accents, a saturated warm-sun palette, and rounded 18px cards with soft colored shadows. A bold friendly rounded sans. Energetic, sunny, vacation-poster vibrant.

Color palette — Mango Teal:
Background #FFF3DC. Leaf motifs teal #1E9E8C. Accent mango #FF9F1C. Text #2B2114.

Typography — use these exact font families:
- Headings / display: "Nunito", "SF Pro Rounded", -apple-system, 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).
