/* HairRank — the visual system for a paid research publication.
 *
 * Two rules run through everything below.
 *
 * 1. The page is not the report. The report is a 40-page document set at
 *    reading size; the page that sells it is a specification sheet. So the
 *    type scale here is deliberately smaller and denser than the PDF's, and
 *    long prose is set as indexed tables rather than as stacked paragraphs.
 *
 * 2. Structure is drawn with hairlines and tabular figures, never with cards,
 *    shadows or gradients. The one shadow on the page belongs to the report
 *    object itself, because that is the only thing here that is meant to read
 *    as a physical thing you are buying.
 *
 * Mobile first throughout: every module is composed at 393px and then given
 * room, not composed wide and then squeezed.
