/**
 * Variant CSS: cta-banner--minimal-rule-centered
 * Layer 2 — Path B cta-banner role (2026-06-06).
 *
 * An ultra-minimal, centred page-closer: a thin accent rule, an eyebrow, ONE
 * headline, ONE button, then a second thin accent rule below. NOT a colour band
 * and NOT a box — the twin framing rules + whitespace carry the whole thing.
 * Distinct from editorial-oversized (huge display + deck + 2 CTAs, single top
 * rule) and boxed-centered (bordered island on a band). Text stays --ink
 * (polarity-aware → contrast holds on any section shade; never --bg-main as
 * foreground, KI-020-safe); accent lands on the eyebrow, the headline <em>, and
 * the single CTA.
 *
 * CENTRING (A8/A9): every centred child (kicker, headline, the two rules) keeps
 * horizontal-auto margins — never margin:0 0 X 0 — so WordPress constrained-
 * layout's margin-inline:auto is preserved and nothing left-pins.
 *
 * All selectors scoped to .universal-cta-banner--minimal-rule-centered — no leak.
