/* READERP panel.
   Self-contained: an on-premise panel must work without reaching a CDN.

   Built to be scanned, not read. A manager opens this between two meetings:
   the figure that needs attention has to be findable in about two seconds,
   which is why colour is reserved for status and nothing else competes. */
