/* ============================================================================
   Transactions — the Caçatais ledger.

   A register spread: the position (balance, escrow, lifetime in and out) and
   the filter rail sit in a sticky side column, the movements themselves run as
   a dense hairline-ruled table in the main column. Day headings carry the date
   so each row only carries its time.

   Colour is spent only where the system's semantics apply — violet for value
   held, green for solved and for money in, red for a penalty. Money out is
   body ink with a minus sign, not alarm red: spending Caçatais is what the
   platform is for, it is not an error.
