/* Spark Business Lending — the journal.
 *
 * The only site here that publishes writing, set like something that does:
 * a contents page in three departments at the head of every page, a front
 * page that opens on the three most recent pieces, and a reading measure
 * because nine of the twenty-one pages are five hundred words long.
 *
 * What it is recognisable by in greyscale: a ruled contents page of
 * twenty-one entries with a note beside each, and articles set in a serif at
 * a reading size with a dated byline above the headline.
 *
 * Merriweather over Lexend. The brand's blue is #20409a and measures 9.15:1
 * on this paper, so it carries text anywhere. The orange is #f1592a at
 * 3.34:1 and never does — it is a rule and a mark, and any text that wanted
 * to be orange takes --orange-deep at 5.44:1 instead. That is the lesson
 * Clear Path and Bloom arrived at the hard way, applied before rather than
 * after.
