You are a founding designer at an AI infrastructure startup. Build a complete one-page site for a fictional product called Vectorline ("Ship agents that don't hallucinate your roadmap."). Real copy throughout, written with dry engineer humor. No lorem ipsum.

ART DIRECTION — terminal noir. Background #070A08 with a faint animated grid: 1px lines in rgba(51,255,153,0.06), a soft radial glow following the hero. Primary text #E6F4EC, muted #7C8A81, accent phosphor green #33FF99 used sparingly (never for body text). Cards #0E1512 with 1px #1C2620 borders, sharp 6px corners. Fonts via Google Fonts: "IBM Plex Mono" for headings, labels, and anything numeric; "Inter" for body paragraphs. Mood: command line, precision, quiet confidence.

LAYOUT, top to bottom:
1. Slim nav — mono wordmark "vectorline_", three links, green outline "Get access" button.
2. Hero — left-aligned. A mono eyebrow like "// agent infrastructure", a big headline where the last word is typed and retyped by a typewriter effect with a blinking block cursor, a one-line subhead, then a fake terminal window (traffic-light dots, three lines of prompt/response that type themselves once on load).
3. A "capabilities" grid — six cells, each with a mono keyword (route, guard, trace, cache, eval, deploy), one plain-English sentence, and a thin green top border that draws itself on reveal.
4. A code-and-claim split — left: a styled code block (HTML/CSS only, no highlight library) showing a six-line fictional API call; right: three short claims with checkmarks.
5. Benchmarks band — a horizontal bar chart built from divs, bars animate to width on scroll, mono value labels.
6. Footer — mono, minimal, with a green "status: all systems nominal" line.

MOTION: typewriter loop cycles three words (agents, evals, guardrails) at a readable pace; terminal lines type once, 24ms per character; grid glow drifts subtly; bars and border-draws animate once on IntersectionObserver reveal; hover on grid cells shifts the background one shade lighter. Respect prefers-reduced-motion: render everything static with the first word in place.

RULES: responsive at 375 / 768 / 1280 (grid goes 3-then-2-then-1 columns). Semantic HTML, focus states, contrast at least 4.5:1 for body text — the green is for accents and labels only. All visuals are CSS or inline SVG. Page must read perfectly with JavaScript disabled.

03
Layout spec

Section by section, top to bottom — nothing left to chance.

04
Motion spec

Entrances, scroll reveals, hovers, and timing curves.
