/* Chat fit (H54): rules for the assistant window on the Hub page only (the widget itself is untouched).
   1) the window never covers the header; 2) the arrow button and the blue corner work at EVERY window height
   (the widget only styles them for windows taller than 680px); 3) page content steps aside when the chat opens.
   --xh-head-b / --xh-chat-w are measured once per open by hub-chatfit.mjs, never while the window is dragged. */
