/**
 * MSS-style newsletter overlay prompt.
 *
 * Everything is scoped to .mss-prompt (a class on the outer Group block in the
 * prompt content) so nothing here can affect the rest of the site. Selectors
 * inside the form deliberately target plain elements -- input[type="email"],
 * button -- rather than Newspack's own class names, because those class names
 * change between plugin versions and the form block may be either
 * newspack/reader-registration or newspack-newsletters/subscribe.
 *
 * Tweak the custom properties in the first block to restyle the whole prompt.
