This is the public host for the Momentum Concierge chat widget. The widget is loaded into client websites as a single script tag:
<script
src="https://widget.momentum-wp.com/concierge.js"
data-site="velocity"
data-business-name="Velocity Web"
data-primary-color="#1a1a2e"
data-greeting="Hi! How can I help you today?"
data-phone="01392 000000"
data-widget-secret="(production secret)"
defer
></script>
Per-site configuration via data-* attributes. The widget talks to the worker API at chat.momentum-wp.com.
For setup details see the deploy runbook.
