/* audit/style.css -----------------------------------------------------------
   Shared styling for the Okanagan Lake Water Audit.

   The palette is LIFTED VERBATIM from the outlook site (web/index.html), not
   re-picked. Those hues were validated with a contrast + colour-vision-deficiency
   checker rather than chosen by eye, and re-picking them here would silently
   discard that work while looking identical to a sighted reviewer on a good
   monitor. Two sites in one family should also not disagree about what blue is.

   PRINT IS A FIRST-CLASS TARGET, not an afterthought. The whole point of the
   handout page is that a utility manager prints it and puts it in front of a
   council, so print rules live beside the screen rules and are maintained with
   them -- not bolted on at the end where they rot. */
