Holographic 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 — Holographic:
An iridescent shifting-rainbow gradient sheen across card surfaces and buttons, like a hologram sticker, with thin white specular highlight lines at 20px card radius. White or near-white text carries a soft glow. Futuristic, shiny, collectible-card aesthetic.

Color palette — Black Holo:
Background #000000. Sheen gradient #7CFFE8, #FF7CD6, #FFE87C. Text #F2F2F2.

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