HTML Support

EVOLV Key Rules
- Use
layout: "row-spread"for status lines (label left, value right). - For multi-field status, build a formatted string in the Function node and send as single payload.
- Keep text widgets
height: 1for compact status rows. - Use
format: "{{msg.payload}}"(the default) — keeps it simple. - For direction arrows and styled status, use HTML in payload:
