/**
 * Algo4Retail — baner systemowy [algo4r_system_banner].
 *
 * "Nobrainer" baner komunikujący, że Trend Nawigator to automatyczny system
 * stale monitorujący rynek złota/srebra. Bohaterem jest flow "Jak to działa"
 * (Dane → Model → Sygnał → Decyzja). Zero JS, zero obrazów — czysty CSS + SVG inline.
 *
 * Wszystkie selektory scoped pod .a4rs (klasy .tile/.flow/.step/.how/.locked są
 * generyczne — bez scope kolidowałyby z motywem). Keyframe a4rs-pulse — własna nazwa.
 *
 * Paleta i typografia spójne z dashboardem Trend Nawigatora oraz banerem Premium (.a4rb).
