/**
 * Variant CSS: newsletter--incentive-split
 * Layer 2 — Path B newsletter role (2026-05-31).
 *
 * Two-column value exchange. LEFT column makes the case (kicker + headline +
 * a short benefit list with custom check markers — what subscribers get).
 * RIGHT column is a self-contained signup card: a visual-only email field
 * (a styled paragraph, NOT a real input — no data is submitted), a real
 * wp:button, and a privacy / no-spam fine-print line. Reads as a confident
 * offer, not a bare field.
 *
 * Field-as-paragraph (no wp:html): keeps the whole section native + editable.
 * All surface colours come from semantic theme tokens; all spacing/type from
 * the universal skeleton ramp (--space-*, --text-*, --tracking-*). No raw hex
 * on theme surfaces.
 *
 * All selectors scoped to .universal-newsletter--incentive-split — no leak.
