 * Newsletter - public styles: the sign-up form ([cbtt_newsletter]) and the

 *
 * Colours and radii come from the suite tokens (--cbtt-*) with plain fallbacks,
 * so the form also looks right where the tokens are not loaded. No style
 * attributes anywhere; everything is scoped to .cbtt-newsletter and
 * .cbtt-newsletter-landing. Tap targets 44px, body text 16px.
