/* The hero, the year comparison and the static 2021-to-2022 stress strip in
 * "Bitcoin vs Gold vs the S&P 500: The $1,000 Investment Test".
 *
 * Every rule is scoped to .post-page and a bgs-* class, and the shared colour, radius and shadow
 * tokens come from styles.css so the light, dark and Auto schemes follow automatically. Bitcoin's
 * bar uses --highlight, gold uses an accessible rich gold and the S&P 500 uses --primary. Colour
 * never carries an answer alone: each bar has its asset name and rounded dollar value in text.
