/* Newsletter, German and English (../newsletter/ and ../en/newsletter/): their words beside their Brevo signup, then the
   archive of past letters. Loaded after ../site.css and ../pages.css. The signup is a real form posting to their Brevo
   address (see form.js); the feedback follows the site's form rule: a ring in the button while it sends, a green drawn
   check on success, the whole card shakes on an error. Media rules at the END. */
