/* ============================================================
   Fusion Observatory — chat-first shell (additive overrides)
   Loaded AFTER styles.css. Turns the classic side-menu layout
   into a dark Fusion frame with a floating white panel, a
   collapsible sidebar (menu + local chat history + user), a
   shared header action set (Search · Feedback · Ecosystem),
   and the zoom/rotate entrance on the Ecosystem constellation.
   The sidebar markup and #sideUser stay intact so auth.js keeps
   working; shell.js only augments them.
