/* Kodza — Subscribe Field
   An email field and its button in one pill. Sent, the button's word rolls away for a turning
   ring (the width never moves), then the pill rises out and the thanks comes up in its place,
   its tick drawing in. A wrong address swaps the hint for the error, like every Kodza field.
   The form posts to its own action (Mailchimp, Brevo, a WordPress plugin), or your code sends
   it: see component.js. The --icon variant trades the word for an arrow.
   Everything is tuned with the --kz-subscribe-* variables. Its width follows --kz-field-width,
   shared by every Kodza form field. */

//   posts the fields there. Another site's answer cannot be read, so it counts as sent;
// - or cancel the "kodza:subscribe" event (detail: { data, done, fail }) and send it yourself,
//   then call detail.done(), or detail.fail("Your message") to show it in place of the hint.
// root.kodzaSubscribe = { done, fail, reset } does the same from anywhere. The failure message
// defaults to data-fail on the form. The motion is CSS.

// Yours to edit: the markup is plain JSX below.

// Built from your data (tabs, rows, options)? Put what the markup is made of in the key, as plain
// values (ids, text, numbers): a change starts the script again on fresh markup. What the visitor
// changes (the open tab, the sort, what they type) is the script's: keep it out of the key, follow
// it with onClick or onInput on the root, and change it from your code as a visitor would (click
