Cyber Noir Plans with Billing Toggle

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 pricing screen with a monthly/yearly segmented toggle at the top showing a "Save 20%" chip, and three compact plan cards in a horizontal scroll row.

Visual style — Cyber Noir:
A near-black canvas lit by a single cold key light — most of the UI stays in deep shadow with one bright focal element per screen. Sharp thin borders, no glow. Condensed uppercase sans for labels. Moody, cinematic, restrained high-contrast — closer to film noir than cyberpunk neon.

Color palette — Blood Red Accent:
Background #0A0808, surfaces #131010. Text #E9E4E4. Key light #E23B3B.

Typography — use these exact font families:
- Headings / display: "Arial Narrow", "Helvetica Neue", sans-serif
- Body / labels: -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).
