A tall portrait infographic tracing the history of money in nine milestones. Background is parchment beige with a sepia-ink central rail running top to bottom. Nine round milestone discs sit alternately left and right of the rail, each labelled with year and form: "9000 BCE: Barter and cattle", "3000 BCE: Mesopotamian shekel", "700 BCE: Lydian electrum coin", "118 BCE: Chinese leather money", "1024 CE: Song paper jiaozi", "1661: Stockholm banknote", "1946: Diners Club credit card", "1973: SWIFT network", "2009: First Bitcoin block". Each disc carries a tiny flat illustration of the artefact in muted bronze, teal, and oxblood. Between discs, the rail is punctuated by small captions explaining the shift in one sentence, e.g. "Trust moves from object to issuer". A headline at the top reads "How Money Got Lighter". A subtle column at the right edge plots "Physical weight per unit value" as a downward-sloping line. Footer reads "A simplified story, not financial advice". Faint paper grain, hairline rules, two-column gutters, small caps for dates.
