Claymorphism OTP Verification

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 phone verification screen with six single-digit OTP boxes, a countdown timer for resending the code, and a full-width verify button.

Visual style — Claymorphism:
Every element is puffy 3D clay: large 32px radii, a light inner highlight along the top edge, a soft inner shadow along the bottom, and a large diffuse outer drop shadow — as if moulded from soft plastic. Chunky rounded sans-serif. Toy-like, tactile, friendly and bouncy.

Color palette — Mint Cream:
Background #DFF5EC, cards #EFFBF6. Text #1F4438. Accents #FFB5A7, #B8E0D2, #F6D186.

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).
