Technical Mono Welcome Slide

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 an onboarding slide with a large illustration area, a bold headline, one supporting sentence, three dot page-indicators, and a floating next button.

Visual style — Technical Mono:
Monospace type for labels, numbers and metadata; clean sans-serif for prose. Sharp 6px corner radii. 1px solid borders, no shadows at all. The accent appears only on interactive elements. Dense, information-rich, precise — like a developer tool.

Color palette — Paper Red:
Background #FAF9F7, surfaces #FFFFFF. Text #1C1B19 / #6E6A63. Borders #DDD9D2. Accent #D0342C.

Typography — use these exact font families:
- Headings / display: "SF Mono", "Cascadia Code", "Fira Code", "Consolas", monospace
- Body / labels: -apple-system, BlinkMacSystemFont, "Segoe UI", sans-serif
- Monospace / data: "SF Mono", "Cascadia Code", "Fira Code", "Consolas", monospace

Commit fully to this style — it should be unmistakable at a glance. Use realistic content, not placeholder text. Keep animations smooth (200ms ease-out).
