ris-draft — Flat Engineering Blueprint Diagrams

Generate one HTML page that renders a technical diagram in a strict flat-blueprint aesthetic — the look of a printed engineering specification sheet, not a marketing landing.

Stack: Tailwind v4 via @tailwindcss/browser CDN for layout + utilities, D3 v7 via jsDelivr CDN for SVG-based diagrams (nodes, connectors, layouts, animations).

Use this when the user wants an architecture diagram, system flow, technical spec sheet, or component map as a standalone HTML artifact (suitable for slides, reports, exports).

Don't use this for:

• Inline schemas inside markdown documents — use a mermaid renderer instead
• Newspaper / reading-first single-column pages with monospace ink-on-cream feel
• Multi-section interactive explainers with pill navigation

Design philosophy

Precise. Objective. High data-ink ratio (Tufte). Every pixel earns its place; nothing decorative. The stack is modern (Tailwind + D3) but the output looks like a printed engineering doc.
