/* ================================================================
   THE TREE — Gazette default layout (2026-08-07)
   ----------------------------------------------------------------
   The baobab tree the diaspora sits under. Two-column spine:
   LEFT  = reading river (single dense column)
   RIGHT = persistent activity panel (Circle · Article chats · Rooms)

   Namespaced under .gazette-tree; scoped `body.tree-mode` toggles
   visibility with the legacy compact grid, gazette-masthead, and
   lead-rotator. Zero touch to existing render code — this layout
   builds from window.CURRENT_NEWS via tree.js wrapping renderArticles.
