Organic Nature 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 — Organic Nature:
Organic asymmetric blob shapes and irregular border-radii (e.g. 60% 40% 55% 45%) on decorative elements. Rounded humanist sans-serif. Leaf, sun and wave line motifs. Soft natural shadows. Grounded, calm, sustainable and wholesome.

Color palette — Ocean Sand:
Background #F2F6F5, surfaces #E2ECEA. Text #1E2A2C. Primary deep ocean #1F5F6B, accent coral sand #E0A56B.

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).
