/*
 * Header menu panels (KJ Core 1.5.2). A top-level item with the class "kj-mega" opens ONE panel in which its groups
 * (items with "kj-mega__group") stand side by side with their links under them - no menus opening out of menus.
 * "kj-mega--2" = two columns (default three); "kj-mega__all" = the footer row of the panel.
 * Every panel has the SAME width and height (Keivan, 2026-10-06: a different box under each item looked wrong).
 * A panel with few links ("kj-mega--tiles": Services, which since 2026-10-06 also holds the apps) fills that box
 * with tiles - items with "kj-mega__tile": title + the menu item's description (printed by inc/menu.php). A tile's
 * own children are small pill links along its bottom; "kj-mega__feature" is the tall first tile (Classes + Weco);
 * "kj-mega__ext" marks a pill that leaves the site.
 * The classes are set on the menu items by scripts/05-new-menu.sh; menu item ids change on every rebuild.
