/* The panel is read while a call is being dialled, so the priorities are scan
   speed and unambiguous status — not density. Facts, inferences and unknowns
   have to stay visually distinct (§11), which is what the marker colours and
   the kind/provenance tag do.

   No web fonts and no external anything: the CSP in _middleware.js is
