A string containing a strict subset of HTML code. Non-allowed tags will be stripped out.
Allowed tags:
* `a` (allowed attributes: `href`, `target`)
* `b`
* `br`
* `em`
* `i`
* `strong`
* `u`
Use [HTML](https://shopify.dev/api/admin-graphql/latest/scalars/HTML) instead if you need to
include other HTML tags.
Example value: `"Your current domain is <strong>example.myshopify.com</strong>."`
