/* ZecPy Live, data-terminal style (seed 617959318), face: the accent line in Zcash gold.

   Grid at 1440: canvas padding 32 + 32, content 1376 = 448 (scenes) + 24 + 904 (server view).
   At 1920: 1856 = 448 + 24 + 1384. The left column is fixed; the server view takes the rest.
   Right column: KPI strip of 4 equal cells split by 1px rules, then the memo batch, then
   the ledger, all on the column's edges. One gap (24) everywhere. */
