   Carbon Footprint Steel - stylesheet
   ------------------------------------------------------------
   The Decarbonizer's design language, written once. The sandbox
   stylesheet accumulated override blocks, so its live values are the
   LAST rule for each selector; those live values are what is written
   here, in one place per selector. If a rule here disagrees with the
   sandbox, the sandbox has moved on and this file should be re-measured,
   not patched further down.
