/* nav-dropdown.css — UnterhaltsPlan

 * Pure CSS, no JS. Checkbox-hack for native click-toggle on mobile,
 * :hover / :focus-within for desktop accessibility.
 *
 * Color tokens come from each page's existing :root vars
 * (--ink, --muted, --accent, --accent-mid, --accent-light, --border, --card).
