Choose a day to hold the desk
Every desk plays three ways: Log, the reading version; Picture, the same record played out on the board, each slip stamped where it happened; and Diorama, the board's marks on a paper model of the real ground (public elevation data, relief exaggerated as marked; it needs WebGL). Switch with LOG · PICTURE · DIORAMA in the console strip, at any time, without losing your place.
Minutes are reading time: the words each day puts in front of you, at 200 a minute. Greyed scenarios exist only as schema: nothing appears here until every fact in them carries a source, and the build enforces it.
