Flat Design 2.0 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 — Flat Design 2.0:
Large soft-color geometric illustration blocks with simple rounded blob-people figures as decorative accents. Flat solid-fill cards at 12px radius, no shadow, no gradient, no texture. Confident single-weight sans-serif. Clean, friendly, corporate-startup illustration style.

Color palette — Violet Yellow:
Background #FAFAFF, surfaces #F1F0FA. Text #241B3A. Illustration violet #7B5EA7 and yellow #FFC93C.

Typography — use these exact font families:
- Headings / display: -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).
