/* Shared styling for the articles.
 *
 * One stylesheet rather than a <style> block per article, because six copies of a design is six
 * chances for one to drift — and the articles exist to be read, so legibility is the whole job.
 *
 * Light rather than the dark used by the experiences, deliberately. The experiences are theatre
 * and read for four minutes; an article is read for eight and often at a desk, and long-form
 * light-on-dark is materially harder to read at length.
