# Icon Reference

## Rules for Renderer Compatibility (cairosvg / rsvg-convert)

**Never use** `@import url()` for icon fonts — neither cairosvg nor rsvg-convert fetches external resources.
**Always use** inline SVG `<path>`, `<circle>`, `<rect>`, `<text>` combinations.
**Font fallback**: embed font-family in `<style>` using system fonts only.

## Azure Service Icons

Azure brand colour: `#0089D6` (top tile / outer ring).
Service-specific accents come from Microsoft's Azure icon set; use them
as the inner badge fill so a glance still tells you "this is Azure".

**Template (Azure tile):**
```xml
<!-- Azure tile: outer rounded square in Azure blue, inner badge for the service. -->
<rect x="cx-22" y="cy-22" width="44" height="44" rx="6"
      fill="#0089D6" stroke="none"/>
<rect x="cx-19" y="cy-19" width="38" height="38" rx="4"
      fill="SERVICE_COLOR" stroke="none"/>
<text x="cx" y="cy+5" text-anchor="middle" fill="white"

For diagrams that need a recognisable "Azure" visual without a service
badge — e.g. a region container or a subscription boundary — use a
dashed Azure-blue outline:

```xml
<!-- Azure region/subscription container -->
<rect x="x" y="y" width="w" height="h" rx="8"
      fill="#0089D6" fill-opacity="0.04"
      stroke="#0089D6" stroke-width="1.2" stroke-dasharray="6,4"/>
<text x="x+12" y="y+16" fill="#0089D6" font-size="10"
      font-weight="700" letter-spacing="0.06em">AZURE • REGION NAME</text>
```
