/* The year-rail timeline behind talks.qmd (see R/talks.R).
 *
 * Deliberately not a card grid: no .item-grid, no JS, no filter chips --
 * just a chronology. Reuses .tag / .muted / .sep / --main-color from
 * cards.css and styles.css (both already loaded on every page), and the
 * talk-type colour rules (.tag--talktype.is-*) that live in cards.css next
 * to .tag--status.is-*.
