Professional Technical HTML Document – Fuel Injection System Engineering Guide (SVG + Advanced UI) -- 2

I have a fully outlined technical guide on fuel-injection systems that now needs to be turned into a polished, browser-ready document. The content is already drafted; what I need from you is the engineering-grade presentation layer and the deep-dive explanations that make the material stand out.

Scope
• Shape the narrative so the engineering-level explanation is crystal clear, with special attention to ECU logic and sensor integration.
• Build a modern, responsive HTML5 layout with clean CSS and a dark, “engineering documentation” aesthetic.
• Illustrate key processes—especially the ECU logic pathway—using crisp, label-rich SVG diagrams.
• Structure each section with semantic headings, expandable callouts, data tables, and flow diagrams where they add value.
• Compare common-rail, GDI, and MPI systems briefly, while keeping the injector anatomy and timing discussion concise yet accurate.

Deliverables
1. A self-contained HTML file (or modular HTML pages) with linked CSS.
2. At least three SVG diagrams: overall fuel circuit, ECU sensor feedback loop, and injector timing sequence.
3. Supporting assets (CSS, SVGs, any icons) neatly organized in folders.
4. A short “build/readme” note so I can host the guide instantly.

Acceptance criteria
• No styling frameworks—hand-crafted CSS preferred for lightweight performance.
• Diagrams must scale cleanly from mobile to 4K.
• All technical statements must cite reliable automotive engineering sources (inline comments are fine).
• Final markup validates to W3C standards and passes basic accessibility checks (contrast, ARIA roles on interactive elements).

If you’ve produced similar technical documentation or interactive manuals—especially in the automotive, aerospace, or industrial domains—share a link. I’m ready to start right away and will provide the draft manuscript as soon as we agree on milestones.
