/* Navigation chart, Glass HUD (design/design_handoff_bridge_glass README,
   "Pane C — chart"). One glass instrument: a 48 px grid, world dots over mono
   labels, the dashed 180 px ring round the current position, the dashed
   route with a 44 px destination ring and, under way, the ship triangle. The
   level controls are .gl-seg buttons in the pane head; the text index lives
   in the Helm detail. glass.css loads after this file, so rules that must
   outrank a single-class primitive carry an extra class. */
