   touching once the chart area has roughly 495px to give them both
   room; with the sidebar (330px) beside the content, that only holds
   true above ~840px of viewport width, not 760px. 761-840px is real
   "desktop-mode but narrow" territory (e.g. a laptop split-screen)
   where the general breakpoint alone would still leave them

     positioning math keys off that element's rect, so nothing here is
