Blueprint 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 — Blueprint:
A deep blue canvas with a fine white grid-line texture throughout, thin white 1px construction-line borders on cards, and corner crop-mark ticks on card edges. Technical monospace for labels and measurements. Precise, drafting-table, technical-drawing feel.

Color palette — Classic Blueprint:
Background #0F3D8A, grid lines rgba(255,255,255,0.15). Text #EAF1FF. Accent white #FFFFFF.

Typography — use these exact font families:
- Headings / display: "SF Mono", "Cascadia Code", "Courier New", monospace
- Monospace / data: "SF Mono", "Cascadia Code", "Courier New", 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).
