/*
Form plugin — block styles.

The fields are styled and themed by the runtime, so only two things are defined
here: how the message after submitting opens, and the spinner on the button.

The message sets no colours of its own — it is page content, so it inherits the
site's text styles and needs nothing for dark mode.
