 * Scoping convention (analysis 22 §8.1 item 6, incident #17): every class this file defines carries
 * the ".ca-" prefix, and no rule here targets a bare shared class (.fig, .quote, .cv, .card, .src)
 * with a descendant selector. `npm run lint-css` enforces both halves of this rule.
 *
 * The four kinds of visual in this deck, and how each is marked so a screenshot still says what it is:
 *   documentary  a photograph or scan of a real thing     .ca-plate, with a dated credit in its caption
 *   empirical    a chart plotted from cited data           .ca-chart, with unit, period and source
 *   constructed  a worked example with invented numbers    data-illustrative, with a .ca-illus marker
 *   model        the backbone loop                         .lp-cv (assets/loop.css)
