/* Day counter — additions on top of the shared base.
   (Header comment said "GST calculator": this file was copied from GSTCalc and
   the label was never changed, which is how the 20px radius below survived the
   AAA+++ token pass — it looked like someone else's file.)

   AAA+++ §3.2: the day counter is the ONE floating object on the page. Its
   radius now comes from --radius-lg (14px), not a local 20px pill, and its
   shadow is the single shared --shadow. Nothing else on the page floats. */
