Contributing templates

Templates are SVG files plus a manifest entry. Once contributed, they appear in the editor’s Participants and shape menus next to the built-in templates.

The contribution flow is in the public repo:

What makes a good template

• Drawn at a sensible default size (vehicles around 4–5 m for a sedan).
• A single colour-changeable region marked with a known fill, so the Attribute Panel’s colour picker can recolour it.
• No external font references — text is converted to paths if present.
• Reasonable file size (under ~30 KB for a vehicle-sized template).
