 * Shared floating menu bar — one persistent bar across the whole copy cluster.
 *
 * It is ALWAYS visible and never plays a page-load entrance. Instead its
 * CONTENTS morph between states as you move between pages, seeded by
 * home-menubar.js so the incoming page starts in the page-you-left's state and
 * animates to its own — the bar reads as one continuous element that just
 * reconfigures:
 *
 *   home   [ ☰ | Connect ]      (index-copy.html)
 *   back   [ ‹ Home ]           (projects-copy.html)
 *   back   [ ‹ Projects ]       (case-*-copy.html)
 *
 * Going home → inner: Connect + toggle collapse away, the back pill grows in and
 * its label emerges from behind the chevron (the original Back-button text
 * reveal). Going inner → home: the reverse. This is the single source of truth
 * for the bar on every copy page (home copy included).
