/**
 * Variant CSS: newsletter--testimonial-backed-signup
 *
 * Social-proof-backed sign-up. Left column is a trust rail on a tinted island:
 * a count chip ("Dołącz do 4 200 czytelników"), a five-star row, a short
 * subscriber quote and an author card (avatar + name + tenure). Right column
 * leads the sign-up: kicker, headline, one line, email field + button and a
 * note. Distinct from benefits-plus-form (icon reasons) and incentive-split
 * (benefit list): here the conversion driver is a real subscriber opinion and
 * the community count next to the field. Text stays --ink (polarity-aware);
 * kicker, em, stars and the button take --accent / CTA tokens. The email input
 * is a visual placeholder. Part of the `newsletter` role.
