/* ============================================================
   NullSpace — changelog
   ------------------------------------------------------------
   A release is a long document, so it is built like one: a
   masthead that states the version, a rail that holds your
   place, and a column of entries you can filter down to one
   kind of change. Everything keys off the shared tokens in
   styles.css — this sheet adds no new colours, only structure.
