+ * - Switches the hero to 4-square mode (data-hero-mode="four-square")
+ * - Paints 4 cells with the configured images
+ * - Auto-cycles each cell every N seconds, rotating through the pool
+ * - Applies object-fit: cover; object-position: center 12% to ENFORCE
+ * the "never show image with header" rule
+ *
+ * Drop-in: <script src="/hero-4grid.js" defer></script>
+ *
+ * Per-site override: set window.Hero4GridConfig = { url, autocycle } before load.
