/* Discrepancy — shared styles for the write-up and the demo.
 *
 * Set like a technical document rather than a product page: one column, generous measure, and a
 * monospace face wherever the page is showing something the system actually produced (a notice, a
 * page of a document, a row of the audit record). The distinction is load-bearing — a reader
 * should be able to tell at a glance which words are mine and which are the system's output.
