Create professional, dark-themed architecture diagrams as standalone HTML files with SVG graphics. Use when the user asks for system architecture diagrams, infrastructure diagrams, cloud architecture visualizations, security diagrams, network topology diagrams, or any technical diagram showing system components and their relationships.

Use these semantic colors for component types:
| Component Type | Fill (rgba) | Stroke |
|---|---|---|
| Frontend | rgba(8, 51, 68, 0.4) | #22d3ee (cyan-400) |
| Backend | rgba(6, 78, 59, 0.4) | #34d399 (emerald-400) |
| Database | rgba(76, 29, 149, 0.4) | #a78bfa (violet-400) |
| AWS/Cloud | rgba(120, 53, 15, 0.3) | #fbbf24 (amber-400) |
| Security | rgba(136, 19, 55, 0.4) | #fb7185 (rose-400) |
| Message Bus | rgba(251, 146, 60, 0.3) | #fb923c (orange-400) |
| External/Generic | rgba(30, 41, 59, 0.5) | #94a3b8 (slate-400) |
Use JetBrains Mono for all text (monospace, technical aesthetic):
<link href="https://fonts.googleapis.com/css2?family=JetBrains+Mono:wght@400;500;600;700&display=swap" rel="stylesheet">
Font sizes: 12px for component names, 9px for sublabels, 8px for annotations, 7px for tiny labels.
Background: #020617 (slate-950) with subtle grid pattern:
<pattern id="grid" width="40" height="40" patternUnits="userSpaceOnUse">
<path d="M 40 0 L 0 0 0 40" fill="none" stroke="#1e293b" stroke-width="0.5"/>
</pattern>
Component boxes: Rounded rectangles (rx="6") with 1.5px stroke, semi-transparent fills.
Security groups: Dashed stroke (stroke-dasharray="4,4"), transparent fill, rose color.
Region boundaries: Larger dashed stroke (stroke-dasharray="8,4"), amber color, rx="12".
Arrows: Use SVG marker for arrowheads:
<marker id="arrowhead" markerWidth="10" markerHeight="7" refX="9" refY="3.5" orient="auto">
<polygon points="0 0, 10 3.5, 0 7" fill="#64748b" />
</marker>
Arrow z-order: Draw connection arrows early in the SVG (after the background grid) so they render behind component boxes. SVG elements are painted in document order, so arrows drawn first will appear behind shapes drawn later.
Masking arrows behind transparent fills: Since component boxes use semi-transparent fills (rgba(..., 0.4)), arrows behind them will show through. To fully mask arrows, draw an opaque background rect (e.g., fill="#0f172a") at the same position before drawing the semi-transparent styled rect on top:
<!-- Opaque background to mask arrows -->
<rect x="X" y="Y" width="W" height="H" rx="6" fill="#0f172a"/>
<!-- Styled component on top -->
<rect x="X" y="Y" width="W" height="H" rx="6" fill="rgba(76, 29, 149, 0.4)" stroke="#a78bfa" stroke-width="1.5"/>
Auth/security flows: Dashed lines in rose color (#fb7185).
Message buses / Event buses: Small connector elements between services. Use orange color (#fb923c stroke, rgba(251, 146, 60, 0.3) fill):
<rect x="X" y="Y" width="120" height="20" rx="4" fill="rgba(251, 146, 60, 0.3)" stroke="#fb923c" stroke-width="1"/>
<text x="CENTER_X" y="Y+14" fill="#fb923c" font-size="7" text-anchor="middle">Kafka / RabbitMQ</text>
CRITICAL: When stacking components vertically, ensure proper spacing to avoid overlaps:
Example vertical layout:
Component A: y=70, height=60 → ends at y=130
Gap: y=130 to y=170 → 40px gap, place bus at y=140 (20px tall)
Component B: y=170, height=60 → ends at y=230
Wrong: Placing a message bus at y=160 when Component B starts at y=170 (causes overlap) Right: Placing a message bus at y=140, centered in the 40px gap (y=130 to y=170)
CRITICAL: Place legends OUTSIDE all boundary boxes (region boundaries, cluster boundaries, security groups).
Example:
Kubernetes Cluster: y=30, height=460 → ends at y=490
Legend should start at: y=510 or below
SVG viewBox height: at least 560 to fit legend
Wrong: Legend at y=470 inside a cluster boundary that ends at y=490 Right: Legend at y=510, below the cluster boundary, with viewBox height extended
<rect x="X" y="Y" width="W" height="H" rx="6" fill="FILL_COLOR" stroke="STROKE_COLOR" stroke-width="1.5"/>
<text x="CENTER_X" y="Y+20" fill="white" font-size="11" font-weight="600" text-anchor="middle">LABEL</text>
