/* Nested nav dropdowns — pairs with nested-nav.js and NavWidget markup.
   Structural only: colors/weights come from the active theme.
   Shipped as NavItemsField runtimeAssets (guests + editors).

   Breakpoint token (override in theme :root):
     --nav-mobile-max: 900px;
   nested-nav.js reads it and toggles html.db-nav-compact (custom props cannot
   appear inside @media). Top-level row layout stays with the theme.
   Compact accordion rules below use html.db-nav-compact only — never a fixed
   @media px that disagrees with a theme's --nav-mobile-max.
   FOUC before nested-nav.js: accepted; see nested-nav.js header. */
