/**
 * Variant CSS: cta-banner--newsletter-band
 * Layer 2 — Path B cta-banner role (2026-06-06).
 *
 * A full-width conversion band built for email capture: copy (kicker + headline
 * + deck) on the left, an email field + button + trust note on the right. Band
 * colour logic mirrors the full-width-accent sibling: band bg =
 * --conversion-band-bg (falls back to --accent), every text token =
 * --conversion-band-text (the theme's contrast pair FOR the accent — paper-on-
 * wine, dark-on-lime) so legibility holds across every theme (KI-020-safe — we
 * never use --bg-main as foreground). The faux email input is a translucent
 * field that reads in band-text colour; the primary CTA inverts to a chip.
 *
 * All selectors scoped to .universal-cta-banner--newsletter-band — no leak.
