/**
 * PageNavigator — CSS Module
 *
 * Styles for the portal-rendered page-navigation dropdown.
 * The root element is injected into document.body via createPortal and
 * positioned with inline `style` (position:fixed + top/left/width/zIndex)
 * so it escapes the header's overflow constraints.
 *
 * Font sizes, list max-height, and dropdown width match the prototype
 * (PantheonP1PuckEditor-PDS.jsx PageNavigator component):
 *   • fontSize: t.sizeS = var(--pds-typography-size-s, 0.875rem)
 *   • list max-height: 360px with overflow-y: auto
 *   • dropdown width: 560px max (set via inline style from positioning effect)
 *   • z-index: 9999 (set via inline style from positioning effect)
