Default (dark / slicr brand)

Drop a single <script> tag — the widget mounts itself right after it.

<script src="/widget.js" defer></script>

Light preset with brand override

Use data-* attributes to theme.

<script
  src="/widget.js"
  data-preset="light"
  data-brand="#e94e1b"
  data-token-in="USDC"
  data-token-out="ETH"
  data-auto="false"
></script>
