/* CHRONICLE — observatory logbook flavor
 *
 * Distinct 4th flavor: deep navy night-sky ground, parchment-cream text,
 * sepia/brass milestone glyphs. IBM Plex Mono dominant (this is a
 * computer logbook), Familjen Grotesk for prose, Major Mono Display for
 * the masthead. Each event is a hand-noted observation; milestones get
 * a ★ rather than a •. Histogram bars are vellum-cream silhouettes on
 * the dark ground. Distinct from cyberpunk (hot/electric) — this is
 * cold/contemplative.
 *
 * No innerHTML anywhere in timeline.js — all DOM mutated via
 * createElement / replaceChildren / textContent.
