/* Email Delivery Tracker — internal reporting view.

   Direction (redesign 23 Sep): calm instrument. Soft, slightly cool-tinted surfaces instead of
   black-and-white; one quiet blue accent for anything interactive; colour otherwise reserved for
   DATA (chart series) and STATUS (small dots, always next to a word). Nothing is highlighted in
   a solid signal colour any more — the old orange pills and bands read as alarms.

   Every text token clears WCAG AA 4.5:1 on its surface in both themes (measured 23 Sep).
   Chart series (blue/aqua) were run through the dataviz validator: dark all-pass; light aqua is
   2.82:1 on white, so every chart ships with a legend and its table (the required relief). */
