/* Einzelhandel / Retail · architecture "Filialrundgang"
 * A spatial walk-through: the hero carries an index of four stations instead of a panel/stamp/switch,
 * the stations follow on a rail (place → what stands out → what we test), then two cases far apart in
 * scale, the PCI DSS Requirement 11 table for the auditor, the ownership gap, modules, FAQ, CTA.
 * Brand: League Spartan via global --font-family, accent #1e88e5, navy #020b17/#030d1d/#041326/#041826, monospace for labels/numbers.
 * Deliberately NOT used here: hero checkmark panel, 4-card icon grid, report-preview mockup, 5-step timeline, 2-column FAQ, KPI band, billboard.
