   China With Me — canonical shared chrome (nav / dropdown / lang / footer)
   Single source of truth. Linked LAST on every EN page so it overrides any
   drifted per-page inline copies, guaranteeing a byte-identical menu bar.
   Fixes baked in: B2 (dropdown hover-gap + bridge), M1 (nav consistency).
