/*
 * The history page (components/HistoryPage.tsx), redesigned 2026-11-04 from the Elementor timeline (cards left and
 * right of an invisible line, centred text): one column like the About pages — the year, the line with a dot, the
 * card — with left-aligned text, a row of year links and a small picture per entry that opens in the lightbox.
 * The hero is the program pages' (components/PageHero.tsx, styles/hero.css).
