/* Notchmeter — site styles.
   The palette is the app's own: Wong's colour-blind-safe set, with #0072B2 as the accent because that is the
   blue the app already uses to mean "needs you, not running out". Dark by default, because the product lives in
   a black notch and a light page would show it as a rectangle floating on white. */
