/**
 * Visual direction: printed, not glassy — the house look, pointed at a market page.
 * Cream stock, full-ink rules, flat panels, hard offset shadow blocks instead of
 * blurs. No gradients, no glow, no backdrop filter. The only two colours in the
 * building are the up and the down, and they are print inks: a dull green and a
 * signal red, never neon.
 *
 * Numbers are the content, so every figure is tabular mono and every column of
 * figures lines up on the decimal. The wordmark and the day number are the one
 * heavy display voice. No webfonts.
 *
 * Dark is the same sheet inverted — night ink ground, cream type, cream rules.
