/* Direction A — the ledger.
 *
 * Two rules run through this file. Codes are set in a monospaced face with
 * tabular figures, because a six-digit number you are copying by eye must not
 * reflow as it changes. And the countdown never goes green to red: blue is the
 * resting state, red is only the last five seconds, and the digits go hollow
 * at the same moment so the colour is never carrying the signal alone.
