/**
 * The one message Taproot sends.
 *
 * Composed in core rather than in the route for the reason `resolveSeo` is: there is already a
 * second caller in prospect — an admin who wants the same link mailed rather than copied — and two
 * copies of this text would drift, with the divergence showing up in somebody's inbox rather than
 * in a test.
 *
 * **No user-supplied content goes in.** Not the recipient's name, not the site title, nothing an
 * editor can type. The HTML part is assembled by hand and never escaped, so the way to be sure it
 * cannot carry markup is for there to be nothing in it that could — `host` comes from
 * `AuthConfig.origin`, which is an environment variable, and the URL is a hex token on a path this
 * code wrote.
