/**
 * Variant CSS: newsletter--full-bleed-band
 *
 * Newsletter sign-up as a full-bleed accent/dark band — the whole section fills
 * edge to edge with a saturated background, with a centered kicker, large
 * headline, one line, an inline email field + button and a short note below.
 * Unlike the boxed-card or stacked variants, here the entire section becomes a
 * strong, high-contrast accent that grabs attention before the footer. The email
 * input is a visual placeholder. Because the band is a dark/accent surface, text
 * is forced to --text-on-dark and the kicker uses an accent lift over dark
 * (KI-020: never use --bg-main as foreground). Part of the `newsletter` role.
